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

Newly developed 24.2MP BSI Full-frame Image Sensor

The newly developed 24.2MP back-illuminated Exmor R™ CMOS image sensor is paired with a front-end LSI that effectively doubles the readout speed of the image sensor, as well as an updated BIONZ X™ processing-engine that boosts processing speed by approximately 1.8 times compared to the α7 II.  This results in high sensitivity with low-noise performance and wide 15-stop4 dynamic range.  It also has the ability to output 14 bit RAW4 format even when shooting in silent5 or continuous mode. Nothing less than spectacular images.

Evolutionary leap in image processing power

The a7 III features a new front-end LSI that effectively doubles* the readout speed of the image sensor, as well as an updated BIONZ X™ processing-engine that boosts processing speed by approximately 1.8 times compared to the a7 II. These powerful components work together to allow the camera to shoot at faster speeds while also enabling its impressive ISO range of 100 - 51200 (expandable to ISO 50 – 204800 for still images and massive 15-stop4 dynamic range at low sensitivity settings. This ensures outstanding overall performance at all settings and in all shooting conditions. 

Up to 10fps1 with Silent5 or Mechanical Shutter

The a7 III is equipped with a refined image processing system that allows it to capture full 24.2MP images at up to 10 fps1 with continuous and accurate AF/AE (autofocus and auto exposure) tracking for up to 177 Standard JPEG images, 89 compressed RAW images or 40 uncompressed RAW images. This high speed 10 fps mode is available with either a mechanical shutter or an electronic shutter for completely silent5 shooting. The a7 III can also shoot continuously at up to 8 fps1 in live view mode with minimal lag in the viewfinder or LCD screen. These high speed options ensure that fast moving subjects can be captured with extreme accuracy and incredible image detail. 

Incredible hybrid autofocus system

The a7 III features a world class autofocus system comprised of 693 focal-plane phase-detection AF points that cover approximately 93% of the image area, 425 contrast AF points and reliable Eye-AF. When combined, both contrast and phase detection AF points form the 4D FOCUS ™ hybrid AF system for wide, fast, reliable AF that locks on and stays locked on. This advanced system delivers AF acquisition in about half the time as the a7 II in low-light conditions with tracking that is approximately 2 times more accurate as well. The acclaimed Eye AF feature is also approximately twice as effective4, and is available when utilizing AF-C mode and with Sony’s A-mount lenses9 with an adapter.

5-step6, 5-axis in-body image stabilization

The 5-axis in-body SteadyShot™ image stabilization system has been fine-tuned to support high-resolution shooting capacity, resulting in an image stabilization system at 5-step6 shutter speed advantage. Camera shake is effectively compensated on 5 axes: pitch and yaw that have the largest overall impact on image quality; X and Y shift that is most apparent at high magnification, and roll that can ruin night shots and movies. Stabilization is applied to the live-view image, making it easier to frame fast-moving subjects. Effective stabilization is provided for movies as well as stills, and for A-mount lenses9 attached via a mount adapter. 

Secure and versatile dual SD media slots

Two SD media card slots are provided for still and movie storage (one slot for SD cards or Memory Stick) with the lower card slot being UHS-II compatible for fast write speed. Still or movie data can be simultaneously recorded to both cards for backup, or RAW4 images can be recorded to one card while JPEG images are recorded to the other. It is also possible to record stills and movies to different cards. Relay recording automatically switches to the second card when the first card is full. Data can be copied between cards while in the camera, for convenient back-up. Sony SF-G series UHS-II SD cards are ideal for situations where maximum transfer speed is required.

High Quality 4K2 HDR3 for the Video Professionals

The a7 III is exceptionally capable as a video camera, offering 4K2 (3840x2160 pixels) video recording across the full width of the full-frame image sensor. In video mode, the a7 III uses full pixel readout without pixel binning to collect about 2.4x  the amount of data required for 4K movies, and then oversamples it to produce high quality 4K footage with exceptional detail and depth. Both S-Log2 and S-Log3 are available for increased color grading flexibility, while HLG (Hybrid Log-Gamma)3 is included to support an Instant HDR (High Dynamic Range) workflow, allowing HDR (HLG) compatible TV’s to playback beautiful, true-to-life 4K HDR imagery. The a7 III can also record Full HD at 120 fps2 at up to 100 Mbps, allowing footage to be reviewed and eventually edited into 4x or 5x slow motion11 video files in Full HD resolution.

The detail of 4K2, the beauty of HDR3

4K2 HDR3 (High Dynamic Range) astonishes viewers with visual depth and impact that are less like conventional movies and television – and more like real life. With the ability to reproduce images from deep shadows to piercing highlights, 4K High Dynamic Range (HDR) is astonishing. With Instant HDR, the a7 III empowers you to capture High Dynamic Range without complex post production. Hybrid Log-Gamma (HLG) recording captures HDR, yet plays back beautifully on both HDR and conventional televisions. For added versatility, the camera also provides S-Log3 encoding.

Long-lasting Z battery

The high-capacity NP-FZ100 Rechargeable Battery has approximately 2.2x the capacity of the NP-FW50 W-series battery giving the a7 III the longest7 rated battery life of any Mirrorless camera at 710 shots8 per charge . The optional VG-C3EM vertical grip (sold separately) houses two batteries and when you need serious stamina for long sessions there’s the NPA-MQZ1K Multi Battery Adaptor Kit (sold separately) that can hold up to four batteries. The NP-FZ100 also supports InfoLITHIUM® technology, which makes it possible to view the remaining battery power as both a percentage display and five step icon on the camera’s LCD screen. Also check out the optional BC-QZ1 Battery Charger.

16-bit processing and 14-bit RAW4 output for natural gradations

Both compressed and uncompressed 14-bit RAW4 format are supported. The 14-bit digital signal from the image sensor’s analog to digital (AD) converter is processed in 16-bit form by the front-end LSI and BIONZ X™ image processor before being output as 14-bit RAW4 data. The result is smoother, more natural gradations that contribute to higher overall image quality. The enhanced BIONZ X image processing LSI makes 14-bit RAW4 output available even when shooting in silent5 or continuous mode.

High contrast 2.36-million dot OLED EVF 

The a7 III boasts a high-luminance 2.359 million dots EVF (XGA OLED) Tru-Finder™ which reproduces the finest details, and incorporates legendary ZEISS T* coating to greatly reduce reflections, while the double-sided aspherical element achieves 0.78x magnification with outstanding corner-to- corner clarity. EVF startup time  when the camera is switched on has been decreased by approximately 40% compared to the α7 II.

  • LOVE IT!! Get this camera from Bedford!!!

    Posted by Amanda Chen on 26th Feb 2019

    I was going to order this camera on Amazon because I know it's a website I can trust if I'm going to spend a lot of money. However, I came here because of the Ad I saw on Instagram. With the same money I was going to spend on Amazon, here at Bedford, I'm getting an extra battery, memory card, and a camera strap!!! So worth it! I would've spent a couple hundreds more if I had to buy those things separately.
    Not only did I get a great bundle deal, but I also got the camera with the one day overnight shipping! The package came with bubble wraps to make sure your camera gets protected! I love how quickly they processed the order!!
    Lastly, I love this camera. I've done tons of research before buying it and it really is amazing. If you want to read more about why this camera is awesome, there are tons of article and videos about it online. I just wanted to come here and write about my experience with Bedford Camera and Video. Happy with my order and the product!

  • This camera is MAGIC!!!

    Posted by Manuel Lemus on 16th Apr 2018

    Save yourself some time and skip through the reviewers on here that have given the camera 1 star because Sony did not include a wall charger! People, we are reviewing the camera not the battery...!!!! Battery charges on Amazon are one. :)

    Anyhow, onto my impressions. I have an a7r2 which is a great camera as well. From my perspective I am basically comparing the a73 to the a7r2.

    The a73 battery life is awesome for a mirrorless body, it can shoot 700+ jpg images without a charge. I used to have to carry 5-7 batteries fully charged with my a7r2, but not anymore!

    Focus Speed and EYE-AF is snappy and accurate. I took some test shots indoor at ISO 6400 to 12k with a moving 10 year old and 90% of my shots were in focus. TOTAL game changer for me with shooting in poorly lit areas and still having sharp image. I would have never been able to get 90% of my images in focus in a poorly lit room with my a7r2.

    ISO perfomance, just lookup some examples on DP Review and other sites. The ISO literally shocked me when I was reviewing my RAW images in lightroom. You can shoot at 12k ISO without issues and for casual shots 25k is also usable. This kicks the a7r2's &^$ in low light and I would even say it is better in low light than the a7s2, images are sharper and color is not muddied on a73 when compared to a7s2 or a7r2.

    Color on the new Sony's is also much better and the images produced with the camera are SO sharp and vibrant, that sensor is MAGIC!

    No camera is are few issue I have that I wish were better.

    Menu system is still very confusing but better than a72.

    Resolution of the EVF and screen are not as high as I would like.

    Screen does not flip out or rotate for video users (I don's shoot video) but still an issue for some. I have not tested but some people have stated that the camera overheats in some cases when shooting for a prolonged period.

    For under 2k this camera delivers on every level. I have enjoyed it and look forward to getting some amazing images.

    Buy from Bedfords, shipment was FAST and package was nicely packed for added safety! Personalized experience was amazing as well. :)
