The Sony Alpha a7S Mirrorless Digital Camera features a full-frame 12.2MP Exmor CMOS sensor and BIONZ X image processor to enable notable video and still image quality with an expansive dynamic range, low noise, and extended sensitivity to ISO 409600. At the sensor level, this full-frame sensor features a unique on-chip gapless lens design, which incorporates small lenses between neighboring pixels in order to increase light-gathering efficiency and promote greater image quality across the entirety of the sensor plane. The sensor and processor combination also avails a wealth of speed throughout the camera system, including a top continuous shooting rate of 5 fps, support for 4K video recording, and a fast 25-point contrast-detection AF system with sensitivity to -4 EV.

Beyond its still image performance, the a7S is also quite adept in regard to recording video. It is able to output uncompressed 4:2:2 UHD 4K video to an optional external recorder over HDMI, as well as record full HD 1080p video in the high-quality XAVC S format at 50 Mbps in multiple frame rates. Extending the video recording capabilities is support for S-Log2 gamma, which helps to expand the effective dynamic range during recording, as well as picture profile options, time code, and zebra marker display aids. Sound can be recorded in the AAC/Linear PCM format via the internal stereo microphone, with a built-in headphone jack for on-board monitoring, or via an external microphone.

Rounding out the a7S's imaging capabilities, both a 3.0" 921.6k-dot tilting LCD monitor and 2.36 million-dot OLED electronic viewfinder are available for image monitoring and review. Built-in Wi-Fi connectivity, with support for NFC, is available, too, for instant sharing of imagery from the camera as well as remote camera control from a linked mobile device.

Full-Frame Exmor Sensor and BIONZ X Image Processor
Incorporated within the sleek body design is a 12.2MP full-frame Exmor CMOS sensor and BIONZ X image processor, which work together to enable an expansive dynamic range with minimal noise and notable sensitivity. The a7S features a native sensitivity range from ISO 100-102400, which is further expandable to ISO 50-409600. Coupled with the large individual pixel size the 12.2MP sensor affords, this camera is well-suited to use in low-light conditions.

The sensor's design also features a new-generation RGB color filter array, as well as a gapless on-chip lens design. Together, these two technologies enable truly efficient light-gathering abilities that further reinforce the low noise, high-sensitivity design. Furthermore, an anti-reflective coating has also been applied to the seal glass of the image sensor to minimize surface reflections, glare, and ghosting for contrast-rich, color-neutral imagery.

The sensor and processor combination also avail a wealth of performance-related benefits to still shooting, including a Speed Priority continuous shooting rate of 5 fps, or a 2.5 fps shooting rate with continuous AF. The contrast-detection AF system employs 25 distinct points to quickly and precisely acquire focus in light levels as low as -4 EV to support working in a wide variety of shooting conditions.
Full Pixel Read-Out with Clean HDMI Out for 4K Recording
Line-Skipping has been the Achilles Heel of video recording DSLR and Mirrorless cameras since video recording was first introduced. Most full-frame and APS-C still cameras have extremely high pixel counts, which is great for still photography, but makes utilizing the whole sensor technically infeasible when recording video since scaling down, say a 36 megapixel image in real time would require a much more expensive image processor and generate more heat than such a compact body could handle. So traditionally these cameras skip lines when recording video, leading to major aliasing and moiré from the large sample gaps as well as decreased resolution and increased noise. However, the lower resolution sensor of the a7S is designed for video recording and features a full sensor readout without any line skipping. This means you will see a sharp image devoid of major aliasing and moiré whether recording internally at 1080p or externally in UHD 4K.

For times when the high quality 50 Mbps XAVC S Codec is not enough the a7S is able to output uncompressed UHD 4K (3840 x 2160) at a 4:2:2 color depth over HDMI to compatible third party recorders. Or, if recording internally to a memory card the HDMI can output 1080p at 4:2:2 for external recorders or HD monitors that don't support 4K inputs. The full list of supported HDMI output signals is:

  • 3840 x 2160 (30p/24p)
  • 1920 x 1080 (60p/24p)
  • 1920 x 1080 (60i), YCbCr 4:2:2 8-bit/RGB 8-bit
Up to 120 fps High Speed Video Recording
In addition to the standard 24p/30p/60i recording formats the a7S is also able to record at much higher frame rates for slow motion playback, albeit at lower resolutions. 1080p video can be recorded in up to 60p using the entire sensor. And 120 fps is possible at 720p using an approximately APS-C sized center crop of the sensor. 120 fps recording allows for about 5x slow motion when played back in 24p.
Customizable Color Profiles and S-Log2 Gamma
To make sure the a7S is able to use its extensive dynamic range while recording video it incorporates extensive customizable color and gamma controls. Users can adjust the gamma, black level, knee, color level, and more. Also users can use the same S-Log2 Gamma Curve that is found on high end Sony Cinema cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased post-production flexibility.
Flexible Timecode Options
The a7S has multiple timecode recording options to meet different workflows. It has the standard 'Record Run" mode that only advances the timecode when recording, as well as "Free Run" timecode that advances the timecode even when not recording, which can be great for syncing multiple cameras at live events. It can also record timecode in both drop frame and non-drop frame modes. When recording internally the a7S is also able to output timecode via HDMI. Timecode output is not supported when outputting 4K over HDMI.
Live Video Overlays
The a7S features many of the same real-time visual overlays and aids that professional video users have come to rely on. These include focus peaking to aid in manual focusing, zebra markers to help judge overexposure, and an audio level overlay for mixing audio. Also focus magnification is available for checking critical focus. These are available in both viewfinder and LCD display.
Audio Input & Headphone Jack
The a7S features a 3.5mm microphone input jack for compatibility with external microphones. And for users needing more the a7S is also compatible with the Sony XLR-k1M XLR Adapter for recording professional balanced XLR audio signals with phantom power and adjustable mic/line inputs.
For monitoring audio the a7S features a 3.5mm headphone jack as well as real time audio levels for a visual reference.
Body Design
Revolving around a compact, sleek body design, the a7S features both a large rear LCD monitor as well as a bright electronic viewfinder. The rear 3.0" 921.6k-dot Xtra Fine LCD features a tilting design (up 90° and down 45°) to benefit working from both high and low angles. Also benefitting visibility with the rear monitor is the incorporation of WhiteMagic technology, which noticeably increases brightness for easier viewing in sunlit conditions. When shooting at eye-level, the 0.5" XGA OLED electronic viewfinder features a high 0.71x magnification and a 2.36 million-dot resolution for precise monitoring capabilities.
Built-In Wi-Fi Connectivity with NFC
Built-in Wi-Fi connectivity enables the a7S to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites. NFC (Near Field Communication) is also supported, which allows for one-touch connection between the camera and compatible mobile devices; no complex set-up is required. Once connected, the linked mobile device can also display a live view image on its screen and remotely control the camera's shutter.

Additionally, PlayMemories Camera Apps are also supported via the built-in Wi-Fi connection, and allow you to personalize the camera's features depending on specific shooting styles. Apps are available to suit creating portraits, detailed close-ups, sports, time lapse, motion shot, and other specific types of imagery.

    Hello, my name is Gerardo Campos of Geco Films.
    We have been one of the few that have had the chance of testing the new photo and video camera SONY A7S. You can find our test in vimeo under this name: "sony A7s test geco english subtitles"
    This is the new camera that has a 4K sensor, with a 4K output
    It does NOT record internally in 4K
    One of its main features is its light sensibility.
    There are some reviews going around on internet, but we wanted to do our own testing.
    We filmed simple shots on the street, since we didn´t have the camera for much time.
    We also tested its slow motion performance, since this camera can work up to 120 fps in 720p mode.
    The camera is small and very light
    Easy to maneuver
    The Menu is fairly well distributed.
    This camera´s light sensibility is phenomenal
    We have some images here. I will show you what we captured on the screen and how the camera delivers the image.
    This camera reaches 409.000 ISO, which is insane.
    We tested it in 409000 ISO, but the truth is that we didn´t find anything dark enough to shoot in that setting without burning.
    I´ll show you some nighttime images of buildings
    The image can be recovered since the camera has a very wide dynamic range
    More than 15 stops points of dynamic range
    You can notice this when recovering the scene.
    When you have a burnt or clipped image, although it seems to be unrecoverable. In post production, as you reduce brightness and highlights you will see how much information is held within the image.
    You can recover invisible image data which may be useful.
    Obviously the camera is noisy in 409.000 ISO, inappropriate for high quality use. However the image could be usable up to 50.000 ISO or maybe even 102.000 ISO, if it were later filtered with Denoise or Neat Video.
    It could be useful in a wide range of instances. Such as documentaries were the camera is used in night vision avoiding infra red. In scenes were animals or insects are photophobic.
    This camera would be great for those circumstances.
    It is a small camera, so its transportation is optimum.
    It is light weight and you can use which ever lens you chose.
    You would only need a small tripod, nothing sophisticated and you would be set to work in scenes with no light at all. It is impressive!

    I professionally shoot high school, club, and collegiate sports. I own the Sony a99 and a7. I love the size, WiFi capability, and everything about the A7. However, on both of my above body's, the 24MP sensor is too noisy above ISO 3200. When I shoot sports, especially indoor sports, such as swimming and diving, I often want to use an ISO of 3200+ to achieve the highest possible shutter speed and lowest noise for a given aperture.When I read about the low-noise, high ISO capability of the a7S, with its large photo site, 12MP sensor, I couldn't wait. When the a7S became available for pre-order, I immediately ordered one. It finally came in, and it met my every expectation except one: When placed in "Continuous Auto Focus" (AF-C) mode, using any of the new FE mount lenses, the camera takes from 1 to 3 seconds to focus. This makes the camera useless for indoor or outdoor, high speed action photography and videography.I spoke to Sony several times about this problem. They agree that the camera's focusing system hunts some before it focus locks on the target. Two different Sony reps said that this is a product of "Contrast Only" autofocus used in the a7S and a7R. My a99 and a7 use "Phase and Contrast" autofocus and they both focus much, much, much faster that the a7S or a7R.Now I can see Sony using "Contrast Only" autofocus in the a7R which is designed more for studio or landscape photography, but why Sony didn't take the slow "Contrast Only" slow focus into consideration for the a7S — a camera that could have revolutionized low-light, high ISO action shooting, is beyond me. What a major shame!If you want to see this for yourself, it's easy. Go to any Sony dealer, mount any Sony FE autofocus lens on an a7S or a7R, select "AF-C" in the Focus menu, and watch how much it hunts and how long it takes to focus when the shutter is depressed half way down.I sent the camera back. If this problem can be fixed with firm-ware, I will buy another one, and update my review to 5 stars. Otherwise, two stars is all it deserves, as I shoot moving subjects. The a7 currently is a much better choice over the a7s or a7R for action shooting.

    Comments about Sony Alpha a7S Mirrorless Digital Camera:

    I shot with Nikon for over 6 years so trading in one of my DSLRs for this setup was a very big step. My choice to swap was to be able to shoot urban photography much more discreetly and for that purpose, this was an excellent choice!The great things are a small physical form-factor. while still providing full-frame output. The low-light ISO performance is unbelievable. Some have called out the 12 MP as an issue but for me, I can honestly count on one hand how many times I've printed 20"x30" so truly, 12 MP is MORE than enough. Also, I'm framing as I would print (minimal cropping). Last point about the 12 MP: I traded in my D700 (12 MP) so I'm in roughly the same place. The silent shooting mode works well - almost creepily well. I haven't used it in fast-motion situations nor indoor so I cannot confirm/deny the banding issue yet, but for outdoor journalistic or street photography, it works well. The dynamic range you're able to get out of a single image is quite good (attaching a vert shot at sunset). My setup is the a7s paired with a Leica 35mm Summilux.I will say that migrating from the D700, one of my current "downsides" is the transition in getting used to a different UI and menu setup. Also, in order for the smaller physical form factor, there are setting/controls that are imbedded into the electronic menu instead of externally. Some customization of the buttons help - but not all custom functions can be associated (hopefully a firmware update of sorts could address?). Other than that, the only other primary downside the battery life. Granted - the a7s sold in the US comes with 2 batteries (I believe I read somewhere else that in other countries it may only be 1?). However, even with 2 batteries, this is the first time I was concerned that I might not last the full day (full disclosure, I haven't run into the problem yet but then again, I had not shot with the rear LCD screen on on my DSLRs in the past so seeing 32% remaining after a half day took me by surprise - perhaps another mental adjustment).Unfortunately, I have not had the opportunity to test out the video capabilities just yet - though I hear this is one of the highlights (apologies!). However, certainly something I look forward to as I use this more.

      This camera is as the reviews suggest - impressive for video, and mediocre in photo.

      The low light is great. I have no trouble bumping it to ISO20,000+ for acceptable results. It's an impressive camera by no doubt.

      Photos aren't bad by any means, just not as extraordinary. I had some issues with the focus peaking, but is that something to rely on anyway?

      Also, watch out for rolling shutter - especially in silent photo mode.

      I bought the a7S with the 55mm f1.8 10 days ago. They performed exactly as advertised. The camera's low light capabilities are remarkable. I've just tried up to ISO 12800 in my lowlight living room, and outdoors at sunset. The lack of noise at 8000 is amazing, and 12800 shots require a minimum of noise reduction in Lightroom The lens is tack sharp. My only negative is that the batteries don't last as long under similar conditions as my Canon 5D MII.

        Comments about Sony Alpha a7S Mirrorless Digital Camera:

        I am not usually big on reviewing products, but this camera is just too amazing for me not to review. I bought it primarily for video work, and I could not be happier. I have been shooting with my 5Dmk3 for the past two years, and I can tell you that after my first gig shooting with the A7s there is no question that it will for now on be my A-cam on everything I do. The image is amazing, and the low light is literally awesome. Seriously. I literally almost cried tears of joy watching this footage. A lot of the work that I do is in Africa and India and am forced to work with what little light I have. This is seriously a game changer for me.A warning though: the rolling shutter is bad. Really bad. Like, shockingly bad. This is not made for action filming with fast pans. Overall, this is the best camera you can buy for the money. The image quality and low light performance beat out any other camera in the price range and may thousands of dollars above it. Do yourself a favor and buy this camera. You'll thank yourself later.

        Comments about Sony Alpha a7S Mirrorless Digital Camera:

        The testes are very good. Everything you would expect from this camera. Our specific tests we're focused on lens fall-off and sensor reaction. The DR was also very surprising, great tonal rendition in the shadows. For this camera the biggest challenge is the infrastructure (for lack of more familiar terms THE RIG). It is important for professional camera crews to use this camera (or any camera) in a traditional fashion, the CINOFLEX, gave the SONY A7S camera that ability. Truly a WOW camera for the quality of the sensor and ability to capture lens fall-off, focus cylinder moves, and the full frame quality image. We are shooting anamorphic Panavision tests soon, that is the true test to see how this camera can make a difference within the marketplace. A very basic and rudimentary test, but this is what we loved about the SONY A7S Camera. Details about this video grab: Camera: SONY A7S PP: SLOG2 Lens: 200mm Stop: T3.1 Color: 3200K SS: 1/50 ISO 3200 ------------- so we shot directly into a light to desaturate the image and lose any detail, then we overexposed by 4 stops. The ungraded image is on the right, the graded image is on the left. With very little effort or manipulation we found good contrast, detail, shadows, highlight control, and sharpness was easily recovered. The lens fall off was also very pronounced and truly magnificent.We think the SLOG2 setting is great, if you can deal with the mandatory 3200 ISO element, but also PP4 with some custom tweaks of gamma and detail knee should give you good performance. Bottom line, the sensor in this camera is far beyond the realm of any consumer image available, anywhere. If you embrace and correctly format a DSLR to your on set environment (I.E. with the Cinoflex) you have an incredible camera on your hands. We do believe that......"The best camera being used by the worst cameraman makes a useless image, but the worst camera with a the best cameraman makes an outstanding image!"

        a7S and a7R — Not for action photograpy

              Comments about Sony Alpha a7S Mirrorless Digital Camera:

              I professionally shoot high school, club, and collegiate sports. I own the Sony a99 and a7. I love the size, WiFi capability, and everything about the A7. However, on both of my above body's, the 24MP sensor is too noisy above ISO 3200. When I shoot sports, especially indoor sports, such as swimming and diving, I often want to use an ISO of 3200+ to achieve the highest possible shutter speed and lowest noise for a given aperture.When I read about the low-noise, high ISO capability of the a7S, with its large photo site, 12MP sensor, I couldn't wait. When the a7S became available for pre-order, I immediately ordered one. It finally came in, and it met my every expectation except one: When placed in "Continuous Auto Focus" (AF-C) mode, using any of the new FE mount lenses, the camera takes from 1 to 3 seconds to focus. This makes the camera useless for indoor or outdoor, high speed action photography and videography.I spoke to Sony several times about this problem. They agree that the camera's focusing system hunts some before it focus locks on the target. Two different Sony reps said that this is a product of "Contrast Only" autofocus used in the a7S and a7R. My a99 and a7 use "Phase and Contrast" autofocus and they both focus much, much, much faster that the a7S or a7R.Now I can see Sony using "Contrast Only" autofocus in the a7R which is designed more for studio or landscape photography, but why Sony didn't take the slow "Contrast Only" slow focus into consideration for the a7S — a camera that could have revolutionized low-light, high ISO action shooting, is beyond me. What a major shame!If you want to see this for yourself, it's easy. Go to any Sony dealer, mount any Sony FE autofocus lens on an a7S or a7R, select "AF-C" in the Focus menu, and watch how much it hunts and how long it takes to focus when the shutter is depressed half way down.I sent the camera back. If this problem can be fixed with firm-ware, I will buy another one, and update my review to 5 stars. Otherwise, two stars is all it deserves, as I shoot moving subjects. The a7 currently is a much better choice over the a7s or a7R for action shooting.

                Comments about Sony Alpha a7S Mirrorless Digital Camera:

                Ever since the dawn of digital photography, my Bessa film SLR and a suite of excellent voitlander lenses have been languishing. When I saw the a7S, not much more than the size of a Leica, I thought the camera would be an excellent for these lenses. I had read about the amazing low light capabilities of this camera, allowing for constant use of speed of 1/250th of a second for almost all shots, without engendering noise or diminishing sharpness, thereby eliminating the need for vibration reduction, given my somewhat shaky hands. I bought the camera and trotted out my lenses after buying the excellent tight fitting new voitlander M to Sony E adapter II, which perfectly mated the lenses to the camera.
                Sony lauds the light weight and small size of the a7series. Unfortunately, this does not tell the whole story, since cameras require lenses and, with the exception of the auto 35mm Zeiss lens, the available dedicated automatic lenses, including the great 58mm Zeiss, are too large for the camera. The 70-200 lens is humongus and heavy. We should have cameras with attached lenses, not lenses with attached cameras. Here, my Voitlander lenses, from 12mm extra wide Heliar to 90 mm Lanthar fit the bill of small size, allowing excellent ergonomics and allowing the camera to behave like a Leica. The 35 mm f1.4 Nokton hits the sweet spot for full frame photography because, at f8, everything between 7 feet and infinity is in focus, thereby allowing a broad range of photography without focus fiddling. By the way, the 12mm Heliar shows almost no vignetting at f8, a great result for the SONY sensor. Steve Huff showed the same thing with the 15mm lens. Now you can add the 12mm as an excellent performer on the a7S.
                Now here's the rub with these lenses, the need for manual focus. This takes some practice, but is easy after mastery. The essential tips are 1, use auto ISO, 2, shutter preference, 3, C1 to magnify, 4, focus peaking to yellow or white medium, 5, focus spot to center focus. The C1 button is close to the shutter release and easy to toggle between. Focus peaking alone will not focus accurately. Use it to get general distance then magnify, critical focus and shoot. Also remember, this is all unnecessary for general use at f8 and above for most general shooting with the 35mm lens because of depth of field. Also f8 is the smallest stop where you can see the image well in the optical finder in bright light. f11 is OK, f16 is not.
                With this advice, the camera functions like a dream. The Voitlander lenses are sharp and accurate and the a7S sensor yields remarkable results. I highly recommend this camera for the purposes I have described. If you went to hang on bigger auto lenses and carry around the extra weight and poor ergonomics, be my guest. Suffice it to say that the a7S fulfills all the criteria and then some for the purpose for which I bought it.

                  I purchased this camera to work on my Movi-M5 and support our Sony F3. I'm using Zeiss glass with a metabones Nikon mount converter and I can not believe the performance and image quality of this little camera. Slog-2 is fantastic. The menu is easy and the camera matches very well with my larger sony production cameras. I'm very VERY happy. I also own a GH4... I listed it for sale the day after I first played with the A7s. AMAZING in low light. Basically no light... Just amazing.

                    This is an amazing piece. I have a RED EPIC that is my A cam, but I needed a second camera that could 1. Do 4k 2. Shoot at least 1080 60p for Jib, RC, and gorilla Run and Gun. 3. Interchange EF glass 4. Durable.

                    Sony has answered the call where canon and nikon haven't.

Low light is several stops better then the a7r. Comes with two batteries. In still mode, it does not get particularly bad battery life, but in Video, it burns through a battery in about a half hour... Dynamic Range is extremely good. Silent shutter is, Silent. No really, it is Silent.

                    Comments about Sony Alpha a7S Mirrorless Digital Camera:

                    Received this today and immediately put it to action. First impressions, small. It goes without saying and if you just read the specs, but this camera is size of a big point and shoot (remember those?). Smaller than the 5D MIII, almost TOO small. I got the Sony battery grip which helps, but with an adapter (metabones speed booster) and lens on it, it becomes very front heavy. I'll be looking for a cage or bracket that fits with the battery grip for more balanced ergonomics. Forget handheld on this camera. You need to have it on something. Handheld, unless you're a statue, is very difficult giving its next to nothing weight. ***Important. I ordered some of the 32GB Sony SD(XC) cards rated at 94MB/s. They will NOT work on this camera if you want to utilize the XAVC codec. The camera will simply not do it, gives an error message. You have to use the 64GB (or higher) version of these cards to access the improved codec. I happened to have a 128GB SD(XC) card, and it fired up just fine. The menu is intuitive and fast. There will be a quick learning curve, but I anticipate it being easy. With the MetaBones adapter and Canon lenses, you need to shoot in APS mode. Having 'APS' off will default the camera to the full frame sensor, which gives crazy vignetting / barreling on a full frame lens (+adapter). The APS mode with a Metabones adapter and Canon L glass looks fantastic. I see this camera being an excellent 2nd camera to the FS700, as with the sensor size and Sony settings, it's very close. S-Log 2 is a good time. Coloring with Magic Bullet or Film Convert yields very nice results. As you know, crank the ISO to 3200 to access the S-Log 2 which is quietly tucked in the Menu under Picture Profiles (PP7). On board mic is actually usable for a reference track, not bad. Quirky con: the 2 strap handles on either side. When you move the camera, it sounds like screws are loose inside. I'd like to remove these sometime soon, no use for a strap.Play with Picture profiles. I found that the "low light" monster everyone is raving about is only effective when you're NOT in S-Log 2. We shot in somewhat dark conditions and it was very noisy. Of course you can adjust this with noise reduction, but it's not optimal. I have to play with this some more to give a more accurate review of the low-light. Overall, very impressed with what this camera can do for its size and price. Looking forward to 4K, but I'll wait to properly record it on a Shogun or Odessey Q7. Image quality: ExcellentForm Factor: Great, but VERY small (get a rig, cage, bracket or something)XAVC Codec: Very robust dynamic range. Full Frame? : Only with a Sony lens. Once you slap an adapter on there, it's APS city - Super35 - still awesome, just back-up. Same as FS700.Great 2nd camera, I hope the vendors start cranking out rigs for it asap.

                    Comments about Sony Alpha a7S Mirrorless Digital Camera:

                    So far, this camera is amazing! I don't have many full frame lens options so I've also used this with my e-mount crop sensor lenses. It seems to do a decent job with those lenses as well.
                    For video the main disappointment is that when you are using the camera with the 120fps option it crops the image down(to crop sensor mode), as well as only doing it in 720.
                    For photos it is definitely a little bit of a challenge working with just 12mp. But you can't beat the low light sensitivity so I'm still stoked on what I have!

                    i use this camera for low light situations (what it was intended for) its absolutely amazing and since it was good at low light, ment it was good for some fast shutter speeds. check out some of the pictures on my sight

                    I've been using the canon 5D's (Mark 2 and 3) for the past 4 years and recently switched to the a7s. I'm blown away by the video capabilities of this camera. The dynamic range is superb, low light is better than anything I've ever seen, the internal compression is great (XAVC), being able to shoot both full frame and aps-c in 1080 make all of my lenses more versatile, and frame rates up to 120fps makes this a killer camera. The only downside is the rolling shutter in full frame mode, but if you have IS lenses or shoot on a tripod it's a non-issue.

                    Comments about Sony Alpha a7S Mirrorless Digital Camera:

                    So far I am really impressed with this tiny camera. It will mix with my FS700 and C100 very well, and it probably spells the end of using my 5DmkII for video, I will keep it and my 7D for stills though.

                    I am working on a sensible kit for it. I have the remote and it works well. I really like the EVF, so the trick is to make a kit that takes advantage of the EVF and still can house the O7Q or the Shogun (on order), I have also heard rumors of much smaller 4K recorders coming soon, this is very interesting. I think by next summer there will be several HDMI 4K recorders out in the wild. And that is fine with me. Right now I really only need HD. 4K is just icing on

                    My initial impression of the A7s is it is a keeper. And it may become one of my all time favs, time will tell. I always go through a longish period of getting to know a new cam, finding a few PPs that work for me. The most important (p)art for me is to match my other cams. Like I said this will be a B or C cam to my FS700. But it also can do things the larger cams can't. And the low light is just astounding. This will probably also become my location scouting cam and all around carry cam. With a Pancake lens it will fit anywhere and may take the place of my GoPros, the pic quality blows them right out of the water. I also see it a a great drone cam, more on this soon.
