Sony A7 III overview

  • 1Description

Distinguished by its updated sensor design, the Alpha a7 III Mirrorless Digital Camera from Sony is a well-rounded camera suitable for both photo and video applications in a variety of working situations. Refined for improved speed and low-light performance, the full-frame 24.2MP Exmor R BSI CMOS sensor and BIONZ X image processor pair to realize an impressive 10 fps continuous shooting rate and improved autofocus performance for faster, more reliable subject tracking along with wide frame coverage. This updated Fast Hybrid AF System employs a combination of 693 phase-detection points and 425 contrast-detection areas for quicker acquirement of focus in a variety of lighting conditions, and also maintains focus on subjects more effectively. In addition to speed and AF, the processing improvements also help to realize greater image clarity and reduced noise throughout the sensitivity range from ISO 100-51200, which can further be expanded to ISO 50-204800. Video recording capabilities have also been extended for enhanced quality when recording UHD 4K video with the full width of the full-frame sensor to minimize moiré and aliasing. Additionally, benefitting both stills and video operation, the a7 III utilizes a 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is now effective to minimize the appearance of camera shake by up to 5 stops.

Beyond just updates to the imaging system, the a7 III's body design has also been revised to include a rear 3.0" 922k-dot touchscreen LCD, which has a tilting design to better support working from high and low angles. A 2.36m-dot Tru-Finder OLED EVF is also featured for bright and clear eye-level monitoring. For greater shooting flexibility, dual SD memory card slots are now featured, and a larger NP-FZ100 battery is also employed to achieve up to approximately 710 shots per charge. Suiting the camera's use in trying conditions, the magnesium-alloy chassis and weather-sealing also render the a7 III dust- and moisture-resistant.

24.2MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor
Featuring a back-illuminated design, the full-frame 24.2-megapixel Exmor R CMOS sensor works with the BIONZ X image processor to offer high-resolution stills and video while minimizing noise and improving speed. This sensor structure works with a gapless on-chip lens design and an anti-reflection coating to improve light collection and enhance detail. Also, the copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution stills with a native sensitivity range from ISO 100-51200, which can be further expanded to ISO 50-204800. Also, it enables internal UHD 4K video recording with a wide dynamic range using the full width of the full-frame sensor. The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with the ability to capture an impressive 15-stop dynamic range at low sensitivity values.

The sensor and processor combination also avails fast continuous shooting at up to 10 fps at full resolution, for up to 177 consecutive frames, and with full-time AF/AE when working with either a mechanical shutter or an electronic shutter. If shooting in live view mode, a continuous shooting rate of up to 8 fps is also possible.
Fast Hybrid AF System
An evolved 4D FOCUS system now employs a combination of 693 phase-detection points, which cover approximately 93% of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and subject tracking performance. This Fast Hybrid AF System now achieves twice the focusing speed and more reliable tracking compared to previous a7 models, as well as improved low-light focusing. The use of phase-detection points also enables the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens mount adapters with full continuous AF/AE tracking compatibility.

The apt focus system also lends itself to a variety of focusing functions for refined accuracy, including Lock-on AF, which maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject, and Expand Flexible Spot, which employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus. Additionally, Eye AF can be used to base focus on recognized subjects' eyes for portraits and is available in both AF-S and AF-C modes. Autofocus can also be used in conjunction with the Focus Magnifier function for critical focus when homing in on minute subject details. The rear touchscreen can also be used for Touch Focus control, and a Touchpad Focus Control mode lets you use the rear screen intuitively while keeping your eye to the viewfinder.
5-Axis SteadyShot INSIDE Image Stabilization
Packed into the robust a7 III is a 5-stop effective 5-axis SteadyShot INSIDE image stabilization system that compensates for five different types of camera shake encountered during handheld shooting of stills and video. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake.

For long focal lengths, the system will correct for pitch and yaw adjustments. Macro and high-magnification imagery, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will get usage out of the roll compensation. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.
UHD 4K Video Recording in XAVC S Format
Internal recording of UHD 4K movies is possible in multiple frame rates up to 30 fps and using 2.4x oversampling renders greater detail and full pixel readout is possible, that is void of pixel binning, for higher quality imagery with reduced moiré and aliasing. Full-frame 4K recording has also been dramatically improved for improved quality when working at mid to high sensitivities to permit full use of the entire sensor width. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both resolutions utilize the 100 Mb/s XAVC S format contained within an MP4 wrapper with 4:2:0 sampling. The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate set to either 30p or 24p. In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.

Affording extensive customizable color and gamma controls, the a7 III allows users to 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. HLG (Hybrid Log-Gamma) support is also available, along with the BT.2020 color space, for recording within a wide color gamut and, in addition to S-Log2, S-Log3 is also available for producing an effective 14-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.
Body Design and Built-In Wi-Fi/Bluetooth
  • An XGA OLED Tru-Finder EVF is featured, and has a 2.36m-dot resolution and 0.78x magnification for bright, clear viewing in high detail. This viewfinder design also affords the use of autofocus in the Focus Magnifier mode as well as improved focusing peaking to benefit manual focus operation.
  • In addition to the EVF, a 3.0" 922k-dot rear LCD is also available, which has a touch panel design for intuitive operation and focusing control. The screen also tilts upward 107° and downward 41° to benefit working from high and low angles.
  • Magnesium-alloy chassis assures rigidity, durability, and stability while remaining lightweight. The lens mount has also been improved to better support heavy lenses and the grip rigidity has been improved for more comfortable hand-holding.

Sony A7 III reviews

Alpha a7 III Mirrorless Digital Camera (Body Only) is rated 4.7 out of 5 by 203.
Rated 5 out of 5 by from Best All-Around Camera This Sony a7III is actually my second Sony mirrorless camera. I bought the a7rIII a few month ago. Although my a7rIII produces higher resolution photos, I'm not too fond of the file size of the 42MP. Unless you have all the latest card readers and computer system, the files from the a7rIII can slow down your workflow not to mention the extra storage space you would need. This a7III is the perfect for that. The operation is practically identical to the a7rIII, and the images are sharp. It's a perfect everyday camera. I've noticed that the evf is not as crisp as the a7rIII, but hey, you save over a grant, so no complain there.

Rated 5 out of 5 by from Ignore Silly "No Battery Charger" Reviews Seriously, You'll give a camera a one star review because it doesn't have an external battery charger? �Big deal, buy one. I go out with two charged batteries and after shooting for many hours haven't touched the second one yet. �When I get home I charge the one I used. �This is an outstanding hybrid camera that excels at both video and stills for $2K. �You can't find a camera at this price point or even higher that comes close. �It's not perfect, but for what it is, close. Sony continues to listen to its customers and continues to improve the product. �Am I Sony fanboy? �No, I am a fan of the leaps and bounds Sony is making with mirrorless ILC's.

Rated 5 out of 5 by from Best hybrid camera - well at least for 2018 I had the GH4 in 2014 for the 4K but the AF and low-light bothered me so I got the a6300 in 2015; loved that so I got the a6500 and waited for the GH5 which was disappointing so I waited for the a7III.� First day of sales the body only� were sold out but the kit lens + body were available for $200 so I snapped it up and got it two days later.�� Excellent camera.� I didn't expect the colors to be better than the a6500 but it is so good to the point that I'm considering getting a second a7iii.� I haven't used the kit lens yet but only with the Zeiss 55f1.8 which is phenomenal.� A corporate client raved about the 4K video with this combo as being Hollywoodesque.

Rated 5 out of 5 by from Huge upgrade from Canon 70D Jumped on the Sony train after years of Canon APS-C bodies. I always wanted to move to a full frame camera and was so excited when Sony announced this (was hoping 6D mkii would be more impressive so I could save my glass). I ordered as soon as I could and am not disappointed! The image quality is astounding. My favorite things about the camera: nails focus every single time, low light performance is incredible compared to what I was used to, 4k video is incredibly sharp, 120 fps slo mo is awesome.� Only thing I really miss is the fully articulating screen like on my 70D. Oh well, I will make the trade for the astounding image quality.

Rated 5 out of 5 by from Amazing product. Love it. This is the fist camera body I've reviewed. I have owned Nikon & Canon cameras, then switched to SONY when we heard of the a7iii release. My fiance and I purchased 2 of them, and the last two weddings we have shot with this camera just made life a lot easier for us. We have tested the battery life on a 12 hour day (which was our primary concern with switching to SONY), and it did the job with just two batteries hybrid shooting both video and stills. We paired these cameras with some Zeiss and Rokinon glass, and we're blown away by both the autofocus performance as well as its low light capabilities. Hands down rock solid product, and highly recommend for anyone looking to do professional work with the SONY systems.

Rated 5 out of 5 by from Huge step forward Ive been using the original A7 as my main camera (mostly for video.) It still gives me some nice images under ideal shooting conditions, but if the light is off or quick focus is required it is definitely showing it’s age. This new camera has been mind blowing in it’s quick focus, improvements to ergonomics, and ability to shoot in low light that rivals the A7Sii. Almost every frustration I had with my A7 has been addressed in this camera, with the bonus of other huge improvements I hadn’t thought of. Stunning low light performance. I was thinking of waiting for the upcoming 7s update ( which might have 10 bit recording), but I have no regrets buying this camera. Love it.

Rated 5 out of 5 by from World Domination It's almost insulting what other manufactures are offering for the price compared to this Sony a7iii. I've been a Canon shooter for 14years, so I have plenty of lenses, but I've made the jump and love this camera. Only issue if you can call it that is video records under another file on SD cards so when you download all your images, you have to download images, then video... not a big deal, but I did format my card for the first time and lost 2 sample videos learning this lesson. I am currently shooting this with the 24-70 f2,8, for families and seniors, indoor events and more... Buy it already...

Rated 4 out of 5 by from great camera with serious flaws I won't repeat what has already been said about the great image quality and low light capability. I only want to mention some flaws that may be critical to some people and that other reviews didn't mention. First, the Eye-AF. It doesn't really work well with fast lenses and shallow DOF. If a person has recessed eyes (most caucasian people), the AF would focus on a brow or nose, but not the eyeball. Second, AF tracking with shallow DOF. It happens in all modes, with face AF, eye AF, etc. The AF would focus somewhere around the ear, rendering the face OOF. If you are not shooting at a very shallow DOF you probably won't notice those problems.
