Canon EOS 70D Review: Dual Pixel CMOS AF, 20.2 MP APS-C Sensor and Wi-Fi


Canon has just announced their newest mid-range DSLR: the EOS 70D. This Wi-Fi-connected camera falls in the EOS lineup between the 60D and the 7D as a high-performance, APS-C-sized DSLR that features the newly designed Dual Pixel CMOS AF technology, a refined 20.2MP APS-C image sensor, and a 3.0” vari-angle touchscreen LCD monitor along with a host of photographic and video-centric assets that combine to form a truly powerful image-making device that can handle video and still photo tasks with ease. Where this camera separates itself from previous models is through its combination of features that strive to generate higher-quality imagery with a rich feature set that facilitates wireless sharing, intuitive navigation and control over camera settings as well as an overall sense of efficiency throughout the entire system.

Dual Pixel CMOS AF

The most refined technology that differentiates the 70D from all past EOS cameras is its inclusion of the newly designed Dual Pixel CMOS AF system, which serves as the successor to the Hybrid CMOS AF II focusing system. When viewing videos of how this focusing system works in real time, it is clear that changing focus between subjects is handled in a smooth and natural manner with no jumping or hunting during focus shifts. It works in a highly intuitive manner with focus quickly changing between the intended subjects and maintains sharpness if the subject is moving through the scene. Allowing for more personalized control, too, Dual Pixel CMOS AF is equally adept at accommodating personal selection of focus points via the touchscreen interface for selective focus and shallow-depth-of-field effects.

This intelligent method of focusing begins at the sensor level and integrates two photodiodes into each pixel, in order to reap the benefits of a broad phase-detection sensor. The 40.3-million photodiodes cover nearly the entire sensor surface, for faster and more accurate focusing that is equally as smooth and adept at locking onto and tracking moving subjects. Having two photodiodes in each pixel helps to provide an inherently more comparative method of focusing from the beginning. Information is split and projected onto each of the photodiodes; the difference in signal from the separate diodes is then calculated in order to quickly determine the focus placement and drive the lens directly to this point. Since the difference in signals is determined prior to moving the lens’s focus position, proper focus can be attained in a single motion with no hunting or shifting. The benefits of this system extend into three distinct areas: speed, ability to fully utilize the LCD monitor in live view, and compatibility with more than 100 past and present EF and EF-S lenses, including the STM series of lenses for enhanced video-recording performance.

Compared to previous iterations of live-view focusing mechanisms, Dual Pixel CMOS AF works to eliminate a camera’s need to hunt for critical focus, and instead can quickly focus on the intended subject. Focus can be acquired in a straightforward and direct manner with no additional time required to measure before and behind the subject; the focus simply locks onto the subject in one single motion. This afforded speed is due, in part, to both the number of photoreceptors as well as the expansive area they cover. While the speed offers the greatest benefit to still-image creation, the focusing is also handled in a smooth manner, with natural transitions between different subjects and when maintaining focus on a moving subject. This fluidity is similar to the way a camcorder focuses and, as such, truly benefits video recording with the 70D.

Expanding this system’s role further, Dual Pixel CMOS AF works in close collaboration with the Touch AF function on the 3.0” 1,040k-dot vari-angle Clear View II touchscreen LCD monitor. This screen’s touch capabilities allow you to simply touch anywhere in the frame to select the point of focus. This is especially useful when recording video and working with rack-focus techniques; the focus shifts from one element to the other in a seamless and smooth manner while focusing accuracy is maintained. The quickened pace and intuitive focusing interface, using the screen, truly allows full use of the LCD monitor as a powerful viewing and composing tool for both still and video applications. While the speed of the live-view focusing isn’t quite as expedient as when working with the optical viewfinder, it is substantially improved compared to previous models’ live-view performance. Extending the monitor’s capabilities is a design that permits easier viewing from high and low angles as well as from the side of the camera. Autofocus can be ensured and reliable no matter what the viewing angle, giving way to a broad range of shooting positions and abilities that were previously more difficult to achieve.

Finally, this focusing system is compatible with a wide range of EF and EF-S lenses: 103 in total at the time of this announcement. This includes both past and current lenses that support this newly developed focusing technology. Furthermore, Dual Pixel CMOS AF supports the recently introduced Movie Servo AF mode, which pairs especially well with STM lenses that incorporate a stepping motor for near-silent focusing. This focusing mode is used when recording videos to provide full-time continuous autofocusing with subject tracking capabilities. When combined with the Dual Pixel CMOS AF system, this mode functions in an even more seamless and responsive way with intelligent autofocusing that can be refined through the Touch AF for selective focusing when recording.

20.2MP APS-C CMOS Sensor and DIGIC 5+ Image Processor

In regard to the imaging performance of the 70D, it utilizes a 20.2 megapixel APS-C CMOS sensor and DIGIC 5+ image processor to produce high-resolution imagery that exhibits a wealth of detail and natural rendering of color and tone. The processing power from the DIGIC 5+ works to enable 14-bit A/D conversion, which helps to produce images with smooth gradations and overall fluency for greater apparent clarity in both photographs and movies. The 20.2MP sensor is the highest-resolution APS-C-sized sensor Canon has ever created, and as such, enables larger file sizes for more post-production versatility and larger print output sizes. Even though the pixel count has reached a new high, Canon has also ensured that the low-light performance of the 70D is maintained, due to the inclusion of the same image processor that is used in their full-frame DSLRs: the EOS 6D, 5D Mark III, and 1D X. Native sensitivity is rated at a range of ISO 100-12800, which is further expandable to ISO 25600, and the 14-bit signal processing helps to minimize visible noise when working with these higher sensitivity levels.

Aside from the image quality attributes provided by the sensor and processor, overall speed and performance is also enhanced throughout the camera system due to this combination. A full-resolution continuous shooting rate of 7 fps is possible, with burst rates up to approximately 60 consecutive JPEGs or 14 consecutive RAW files; full HD 1080p video recording is supported in multiple frame rates with manual exposure and audio level control.

A full-resolution continuous shooting rate of 7 fps

Built-In Wireless Connectivity

Another first for APS-C DSLRs from Canon is the integration of in-camera wireless connectivity for instant sharing and remote-control possibilities. Just as with the full-frame EOS 6D, the free Canon EOS Remote app is available for iOS and Android mobile devices and can control exposure settings (aperture, shutter speed, and ISO), focus, and release the shutter wirelessly, from a distance. Live-view monitoring is also supported on devices during use as a viable means for monitoring subjects within the composed image frame.

Shooting remotely with a smartphone

In addition to camera controls, the wireless feature enables the sharing and transferring of image files directly from the camera to mobile devices, other wireless-enabled Canon cameras, and to network-connected computers. Once files have been transferred to a mobile device, instant sharing via email, social networking sites, and cloud storage sites is possible. Files can be sent to the CANON iMAGE GATEWAY for expedited posting to social media sites, and remote viewing of stills and movies is also possible on DNLA (Digital Living Network Alliance) compatible devices, such as HDTVs and other wireless-connected devices. Wireless printing of photos is also possible straight from the camera when connected to a Pict-Bridge-compatible printer.

The EOS 70D is also compatible with the optional GP-E2 GPS Receiver, which enables geo-tagging and the embedding of locational data into images’ metadata for plotting to interactive maps. Elevation, direction, and Universal Coordinated Time (UTC) are also recorded along with the longitude and latitude of each recorded image.

Vari-Angle Touchscreen LCD Monitor

Serving an array of the technologies housed within the 70D, the 3.0” 1,040k-dot vari-angle Clear View II touchscreen LCD monitor is an efficient and intuitive means for live-view monitoring, image playback, and menu navigation. Its touch capabilities greatly enhance working in live view while shooting by way of Touch AF and a host of other touch-sensitive camera controls. Additionally, it gives way to a more natural method of navigating through menus when compared to working with conventional wheels or dials.

The vari-angle design of the monitor is ideally suited for working from high and low angles, as well as viewing and composing from the side of the camera. When coupled with touch control and the Dual Pixel CMOS AF system, live-view monitoring can now be used to the same extent and set of expectations as an optical viewfinder, giving way to fast and reliable focusing performance with versatile control and viewing abilities that are not otherwise possible. The screen itself features an anti-reflective smudge-resistant coating that makes viewing in bright light easier.

Intelligent Viewfinder and 19-Point AF System

For viewing in a more traditional manner, an optical pentaprism viewfinder is also integrated into the 70D and provides 98% frame coverage for clear eye-level finding. A superimposed LCD monitor is added to the viewfinder’s construction to allow for monitoring of crucial camera settings while viewing and, additionally, focus points, grid lines, and an electronic level can be activated to further aid composition.

When using the viewfinder, a 19-point all cross-type AF system is used to acquire focus deftly, even in difficult lighting conditions. The center point of this system is a high-precision, dual cross-type sensor that is compatible with f/2.8 and faster lenses. The cross-type design of these points ensures their accuracy with a greater range of subjects, and their configurable nature also allows you to tailor their results and use them for specific shooting applications.

iFCL 63-Zone Dual Layer Metering Sensor

The multi-layer 63-zone iFCL (intelligent Focus Color Luminance) exposure metering system is employed for both still image and movie recording in order to accurately depict any scene, regardless of lighting conditions. This metering system utilizes information garnered from focus, color, and luminance in order to set exposure precisely. The 63 zones cover a broad area of the image frame and the dual layer design (one red/green channel and one blue/green channel) works to offset the inherent red-light-sensitivity bias of image sensors in order to produce consistent and repeatable results. Evaluative, center-weighted, and spot-metering methods can be used to determine specific exposure setting results and +/- 5 EV still and +/- 3 EV movie exposure compensation is available when working in program AE, aperture-priority AE, and shutter speed-priority AE shooting modes.

EOS HD Video

Besides the creation of vivid still images, the 70D also supports the creation of full HD 1080p movies at 30, 25, and 24 fps frame rates. When recording videos, manual exposure control is available for refining the look and feel of movies through adjustment of the shutter speed, ISO sensitivity, and aperture setting. In addition to exposure control, audio levels can be adjusted across 64 levels and sound can be recorded using the built-in stereo microphone or with an optional external microphone, connected via the 3.5mm microphone terminal. Sound recording is the beneficiary of an automatic attenuator function that helps to alleviate audio clipping, for cleaner overall sound. Movies are saved using the high-quality H.264/MPEG-4 AVC codec, and video files greater than 4GB are automatically split for extended recording sessions (up to 29 minutes and 59 seconds). Additionally, both IPB and All i-frame compressions are available for use, depending on editing preferences and the final output destination.

Moving subjects are consistently and smoothly tracked for Full HD video that is in sharp focus.

Just as with still shooting, video recording benefits from the Dual Pixel CMOS AF system and its ability to provide smooth focusing that is both controllable and accurate. The Movie Servo AF mode provides continuous focusing during filming with subject tracking and also affords full compatibility with Canon’s STM lenses for extremely quiet focusing. The Touch AF function enables precise control over the exact placement of focus within the scene and is usable during recording as a viable means to control focus without having to touch the lens or move the camera during operation. By using the Touch AF control, rack focusing is possible to help swiftly move attention across the scene and to highlight specific elements in the frame when working with wider apertures, for shallow-depth-of-field shots.

Also serving to enhance creativity with movie recordings is the Video Snapshot mode, which allows recording of movies in clips of 2-, 4-, or 8-second segments and automatically stitches them together sequentially. This compilation of short video clips can then be set to music in-camera and output as one finalized edit—eliminating the need to manually sequence and edit with a computer.

Imaging Modes and Effects

For creatively modifying and enhancing the look of imagery in-camera, a wide array of options can be selected in-camera, ranging from HDR and Multiple Exposure modes to creative filters and scene modes. The High Dynamic Range (HDR) mode will automatically record a series of bracketed exposures in-camera and composite them together, in order to produce a single exposure that has extended highlight and shadow details along with an extended tonal mid-range. This is ideal for high contrast and backlit situations where the difference in exposure values in the scene is greater than a single exposure can record. Similar in approach, yet able to yield more creative possibilities, is the Multiple Exposure mode. When working in this mode, several exposures can be created manually and overlaid into a single file. Two distinct control settings are available for this: Additive and Average. The Additive setting closely resembles the process of creating a multiple exposure using film, in which each consecutive exposure is layered and the final exposure level is built-up across each frame. The Average setting will, rather, blend the recorded exposures into a final exposure that maintains a neutral density in order to avoid extreme under- or over-exposure.

Scene Intelligent Auto mode is an analytical auto-exposure mode that combines many of Canon’s exposure technologies together in order to produce imagery with refined exposure settings. Picture Style Auto, Automatic Lighting Optimizer, Automatic White Balance, Autofocus, and Auto Exposure all work in concert to carefully analyze the scene in order to calculate the most effective exposure settings to clearly render the subject. Also working to produce proper exposures, especially in difficult lighting conditions, are HDR Backlight Control and Handheld Night Scene modes. Both modes work in a similar fashion by recording multiple exposures of the same image and then compiling them in order to produce an image that exhibits reduced camera shake or greater shadow and highlight detail. For creative modification and enhancement of imagery, seven different Creative Filters are available and can be applied during shooting with results visible during live-view shooting.

Lens Kits

In addition to the 70D being available as a body only, it is also available in a kit with either the EF-S 18-55mm f/3.5-5.6 IS STM lens or the EF-S 18-135mm f/3.5-5.6 IS STM lens. The 18-55mm lens provides a 35mm equivalent focal length of 28.8-88mm and the 18-135mm provides a 35mm equivalent focal length of 28.8-216mm. Both lenses provide a range of coverage, from wide-angle to portrait and telephoto lengths, respectively. Both of these lenses are designated as STM lenses, which incorporate a stepping focus motor that helps to produce near-silent results when recording movies. They both also incorporate an optical image stabilization system that benefits image sharpness by the equivalent of four shutter-speed steps through the reduction of the appearance of camera shake.

BG-E14 Battery Grip for EOS 70D

A new battery grip for the 70D is also available to provide extended shooting capabilities and a more ergonomic way to handle the camera. The BG-E14 grip accepts up to two LP-E6 rechargeable lithium-ion battery packs or six AA batteries and is also compatible with the ACK-E6 AC Adapter Kit for constant AC power. The grip design incorporates several operating controls, including a shutter release, main dial, multi-controller, AF point selection button, AE/FE lock button, AF start button, and a multi-function button to increase functionality and operability while shooting in vertical orientation.

canon 70d weather sealed or not....?

The Canon EOS 70D camera is dust and moisture resistant, but not weather sealed to the same level as a top tier model such as the 1Dx would be. 

Great camera

is their wifi in all canon 70 models, or only in some models if yes can u pls recommend a wifi canon 70d model

All Canon 70D’s distributed through Canon USA and carried at B&H have built-in Wi-Fi.  Canon does make a model without Wi-Fi, but I believe this is only distributed in certain regions/countries where the Wi-Fi model would be prohibited.  You can find the Canon 70D kit options we carry at this time if you CLICK HERE

I have just bought one and have two lenses both with STM - 55-250 and 18-55.

But Canon, please listen to your customers and provide the option to just record audio on its own without having to record video at the same time. We don't want to have to buy a stand alone microphone as well! Crikey! Come on Canon! We don't want to have to put all the system into operation and record gigabytes of video just to get the audio. 

Is it worth purchasing a 70d or 7d mk2(after it is available) for coming 4-5yrs considering aps-c 's future ? Or a full frame

Canon system ?


APS-C size sensor cameras can have advantages over full frame.  You can typically find faster burst rates without having to spend 6K.  And they will make your telephoto lenses appear more telephoto.  So, if you shoot sports or wildlife, an APS-C size sensor camera could be a good fit.  The 7D II will have a burst rate of 10 fps, has a magnesium alloy body with a shutter count of up to 200,000 actuations, and an excellent AF system.  It would be hard to go wrong with this camera for sports/action shots and wildlife.

I don't understand why they bother som much about video in dslr cameras?

The only reason to buy dslr for video is when you're video/film class student or something. Or if you plan to film in studio with all the lamps and other crap... For an amateur using dslr for video is a cmpletly nonsense in comparison to dedicated camcorder - you miss almost everything - size, handling, video stabilisation, AF speed, plus many, many other features that are natively implemented in camcorder. You only win capability to change lens and DOF - control. Using dslr for video on a trip is a nightmare...

They should concentrate to make a perfect photo camera. Perfect for still images. Low noise, fast AF, sharp sensor, mor DR and mor features that matter in photography. Canon seems to forget that they make a CAMERA, not CAMCORDER... Sure - video features is a nice addition, but not if they come at a cost of photo capabilities - and this is a case with 70D - they make a sensor that performs better only in video mode. In photo is a virtually no difference to 60D...

I have a EOS 450D and will change camera for something more serius (better grip, better AF, better IQ, but APS-C - i don't need FF) and Canon doesn't have an option for me... 70D (beside new video capabilities) looks like camera from the past... It's no better than old 7D... This is evolution? What's wrong with Canon?

They focus on video in DSLR's because the creativity you can get out of a DSLR cannot be found with a camcorder in the same way. Camcorders are great for production and producing great videos but there is just a lot of great creative ways of producing with aDSLR that you cannot get with any camcorder.

David Busch explains such things with simplicity and elegance in the book, Canon EOS 70D Guide to Digital Photography, which can be found at  The Dual Pixel CMOS provides fast, accurate focusing, including a very smooth and regulated focus pulling function.  The APS-C sensor is much larger than that of a camcorder (of similar prosumer quality), and the full-frame DSLR sensor is even larger, thus many videographers have been using DSLR cameras for high quality video work.  Watch the end cradits of recent videos and films as equipment detils may be listed.  

Can the Cannon 70D wirelessly transfer pictures to an iPhone 5s or to an iPad Air if the is no wifi hot spot near bye?  Example, when I am in the desert or out on the ocean.  Thanks for the clarification.

I know it's quite a while ago, but I just got a 70D and YES, you can Wifi directly from camera to iPhone. There doesn't need to be any other hotspots to achieve this.

The review is great ,

I am a wildlife photographer and I want to select my next camera. I am considering 7D / 70D , I have 100-400 USM IS L lens. Please advise me that which one will be the best camera for me.

1. Speed

2. Low light capability

3. AF performance

is the points to be considered.


 I have an EOS 70D. What is the best way to capture video at night while moving? Is it possible to do it using manual focus? My guess is that if you have something specific you want in focus at some point of a route,  you'd set that focus, then go through or past that object. Things before and after the shots of interest may not be in focus/ lights may be furry, but what you want to capture will be in focus.

I tried AF and parts of the route were in focus, but not what I wanted.

Is there a good simple web sight for night time videos/ photography methods? 

Also if I am running with the camera, whats the best way to stabilize it? Is there a lite harness?  (I am small.) 

Thanks uma 

I want to say that very likely the answer is in your hands. The Canon 70D has the most advanced Live View video auto focus of any DSLR on the planet.  Please look up in your 70D manual pages 233 to 250 regarding focusing with your camera. You should be able to select subject and the camera will keep it in focus while the camera or the subject moves.
There is a caveat. If the light is too low, then it's very possible the Auto Focus will not work. Cameras are, at their basic level, light gathering devices and if there is no light, it has difficulty doing it's job.
If the light level is very low, then you may have to learn how to "follow focus" or manually adjust the focus on the lens in order to have the subject clear and sharp  This is in fact how it is done on professional movies, for there is an assistant cinematographer whose main job is just adjusting the focus on the lens at all times the camera is rolling.

For running with the camera, the best option would be to get a Stedicam unit for the camera. 

why the 70D?

I admit that I would prefer a full frame sensor for the better light sensitivity (less noise at high ISO levels) but there are mainly two reason that full frame bodies are not an option:

1. no build in flash (I use it very often as fill flash and do not want to carry an external flash)
2. no vary-angel screen (I need to shoot often over head)

(some additional reasons against full frame are: bulky and/or heavy heavy, expensive)

Live view is great if you have lenses with wider aperture than 2.8. Using a viewfinder you cannot not see a difference in depth-of-field if the aperture below f2.8 but in live view you can. With my 7D or 60D I often use live view with manual focus (before the 70D autofocus was terrible slow and not accurate) but now with the 70D you can just touch the back screen where you want to focus at.

Just want to know your thoughts about the 70D vs. the 6D. I'm switching to Canon from Nikon. I do mostly travel, landscape, and nature shots. still a learning the world of DSLR, newbie. I love the 24-105mm lens and think it might be a waste on the 70D as the crop factor causes you to loose something I think. Thanks.

What SD card do you recommend for this camera? Is the Scandisk Extreme Pro worth the extra money when used with the 70D?

My current number one camera body is the 1D Mark II... it's an awesome camera that still takes great images... (mostly long-lens nature photography.) It's hard to believe I've had it as long as I have. It's time to move up - more pixels mean more flexibility when it comes to cropping.... I'd like to get into the video side and I want to stick with ASP-C to benefit from the longer effective reach that I have with my 1D Mark II.

The next logical step would seem to be the 7D... if not for the fact that the 70D offers roughly the same key features for still photography and some really interesting video advancements. By the time you add the battery grip to the 70D, it's about the same as the current price as the 7D... and likely half of what the 7D Mark II might cost if/when it's released.

I'd be curious to know which way Bjorn and the other experts would go if they were in my circumstance... 7D or 70D?

Thanks for the advice.

It is like the people in Canon do not listen to their customers. They have sold a bunch of cameras like this in the video market. Why for the hell, they do not inclued a headphone output for audio monitoring???

All this negativity? Who cares about the small stuff? Are you in the habit of dropping your gear? If not then why moan about the plastic body. I haven't heard of a single 60d that fell apart a few months after purchase. And cropped sensor? If you don't like it then don't buy it. Go spend thousands on lenses which will get you closer on your FF then. This camera gives you decent build, a new sensor (which I would want to see the performance of), AF from the 7d, DIGIC 5+ processor, micro adjust, built in speed light trigger. If that's not good enough go buy something else. Jeez

The major improvement over the 60D is in video focus. This is very important to me & I will upgrade to the 70D or even the 7D II (or whatever it's name will be), when ever it is available. But, if you don't intend to use your DSLR for video, save your money. The improvements in 70D photo don't justify the extra $$$.

Just thought I'd add my thoughts on FF vs APS-C commits by others. It's all about light capture. APS-C at 22.5 x 15 mm will never match FF at 36 x 24 mm. FF is physically 2.5x larger. So, the main visible difference is photos shot at higher ISOs will look better using FF, lower ISOs not so much.

And, why all the fuss about crop factor? Who cares? 50mm FF lens equals 80mm on APS-C. If you want a lens close to 50mm normal using APS-C, a 30mm FF lens equals 48mm on APS-C. Why is using a little math that a big deal?
BTW - many newer lenses are designed for APS-C so no crop at all. If it's truly an issue, FF DSLRs start at $2k & go up from there. Take the plunge; be satisfied knowing it's "better".

Is this a full frame or not? Why is it so difficult to find this info??

No, the 70D is not a full frame camera! You probably figured that out by now.....

Not much of an upgrade but I will take a look at it. a few points just from reading the specs here:
Aperture way small, how about 2.5 or under? I know, COST!
CF cards are old and slow so of course all the SD's would be better, plus more gigs.
Last round I went for the Nikon D90 as it had faster continuos shooting, Solid Body, and multiple lenses included, but getting sharp images was a task of setting on the fly. Some were good, most not.
I want a camera semi-pro/pro that I can take pictures and and know that they will be sharp and clear as I use Photoshop and other software as well and don't need to spend hours to try to fix a blurry picture.
All the extras put into making fancy scenes like "Fireworks" or even in camera editing would be better used making a universal lens mount, lower aperture.

I have seen some Point and Shoot cameras that blow away the semi-Pro cameras. Dump the MOVIE mode on semi-pro, its always bad.

Just a camera that you can take good clear sharp pictures with and feels solid as it should.

this 70D sounds like it is a definite improvement over the 60D, but ..
my question is this: the 60D is relatively new, while the 7D is getting old !!!! Why didn't canon give us an improvement on the 7D.
It sounds like the 70D might be shoveling dirt on my 7D. I love my 7D and would Love to get an upgrade to it, not have to take a step down to the 70D. come on canon, let's get going, and while we're at it: why don't you give us an 18-300mm lens like nikon ? please ?

I am currently using a 30D with great results so what is the new version 60d 70d 6d etc. These seem plastic compared to mine i don't need video

It's tempting but is the body all plastic like the 60D?

Well, there's a few things that I would NOT want...

- I don't think HDR is necessary. I want to pick what the best version is and the battery power for internal processing is the main reason that I avoid EVIL cameras.

- In the field... touch screens are... ugh.. messy. I'm constantly cleaning my phone and tablet. AND... extra battery power.

- You can tell me that an add-on battery pack is ergonomic, but try hanging those things from your next on a long hike.

HOWEVER, I like the new focus and am curious about the SIA. And, as long as you keep making the lenses compatible, I'm happy :).

It's bad enough that CF cards can't be used, but if this body also does not feature autofocus microadjustment capability, then it, too, is just another toy camera, and not worth purchasing, just like the 60D.

Canon why oh why can't you make up your mind on memory cards?
ok so now what do I do with all those cf cards I have?
this "new" 7d takes sd cards and NOT CF!!

Memory Card Type SD

I love the sd cards as I also carry around a small camera in the car for the just in case. oh well.

Looks like a very slightly reworked 60D. In fact, some of the specs are worse...

Add a "vari-angle; tilting" monitor to a 6D and I'd buy it!

I may buy this simply for the auto-focus enable in video mode... Since having the STUNNING 5D Mk. III, the only complaint is Manual Focus in Video!!!
I wonder about pix quality from a smaller sensor... Ya get spoiled with the Mk. III????

Why, why, why can't they get away from APS-C sensor? I don't want a 1.5x factor on my lenses. I am still using my D60 (yes the 2002 model) and that has kept me from buying anymore DSLR's from canon on the D-line until that is replaced. I want the Mark-III but $3,000+ on the body is harsh. Wish they would make a 70D+ that had the other sensor and same features. I would pay extra $500 for that. Thank goodness for iPhone to save me on my close ups.

Maybe I'm missing something, but if it's 98% of FF in an APS-C, why not just change the sensor and make it full-frame? Is there THAT much difference in cost?

Because of the encreased resolution Individual Pixel Photo diode size has being brought down from 4.3 to 4.0 micrometers. This means even less sensitivity to light.

I want it I want it I want it!!! Wow the remote capability is a real grabber!! To be able to set up a shot in nature and shoot remotely is just awesome. Now to afford it! Ugh

the film is stunningly satisfying—taking a seemingly 'ordinary' no-drama subject, telling a story with beginning middle and heart-full end, so clear. so clean—I shed a tear, I admit it!

It will be such a bad news to hear that the new 70D's CMOS bought from samsung. You see, the Canon APSC size is the size on 60D, and the regular APSC size is on 70D, so it's pretty obvious that Canon bought sensor from other company and this reveals that the CMOS manufacture technology of Canon is pretty bad now.
