Spectacular 42.4MP full-frame resolution
The 42.4MP high-resolution, back-illuminated Exmor RÂ® CMOS sensor utilizes a gapless on-chip lens design and AR (anti-reflective) coating on the surface of the sensorâs seal glass to dramatically improve light collection efficiency. This results in high sensitivity with low-noise performance and wide 15-stop4 dynamic range. No optical low pass filter maximizes resolution, while also having the ability to output 14 bit RAW15 format even when shooting in silent or continuous mode. Nothing less than spectacular images.
Evolutionary leap in image processing power
The a7R 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 a7R II. These powerful components work together to allow the camera to shoot at faster speeds while also enabling its impressive ISO range of 100 – 32000 (expandable to ISO 50 â 102400 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 Silent or Mechanical Shutter
The a7R III is equipped with a refined image processing system that allows it to capture full 42.4MP images at up to 10 fps1 with continuous and accurate AF/AE (autofocus and auto exposure) tracking for up to 76 JPEG / RAW images or 28 uncompressed RAW images11. This high speed 10 fps mode is available with either a mechanical shutter or an electronic shutter for completely silent shooting, adding to the immense flexibility of the camera. The a7R 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 upgraded focusing system of the a7R III is comprised of 399 focal-plane phase-detection AF points that cover approximately 47% of the image area in both the horizontal and vertical directions and 425 contrast AF points which cover approximately 68% of the image area (an increase of 400 points compared to the a7R II). When combined, both contrast and phase detection AF points form the 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 a7R 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 Sonyâs A-mount lenses with an adapter12.
5.5-step7, 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 the worldâs highest10 compensation performance for an image stabilization system at 5.5 step7 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 lenses attached via a mount adapter12.
Low-vibration high-reliability shutter
Thanks to a new shutter unit with a fast-response coreless motor and a brake system, front and rear curtain mechanical shutter vibrations that can cause blur, is subdued to a minimum, while allowing high-speed continuous shooting at up to 10 frames per second. The shutter is also quiet, and has been tested for durability in excess of 500,000 shutter cycles4. Low-vibration high-reliability shutter helps to maximize 42.4 effective megapixel performance and enables 10 frame per second shooting with high speed studio strobes.
Pixel Shift Multi Shooting8
In a ânormalâ digital capture each pixel represents just one color: red, green, or blue. The surrounding pixels are used to supply the necessary extra information required to interpolate and reproduce the remaining two primary colors. Pixel Shift Multi Shooting8 takes advantage of the advanced in-body image stabilization system. It precisely shifts the sensor in 1-pixel increments to capture four pixel-shifted images containing a total of approximately 169.6 million pixels8 that are later composited using supplied software running on a personal computer to achieve overwhelming subjective resolution in a single 42.4MP image. Still images of subjects such as architecture and art are captured with true-to-life details, texture, and color.
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 RAW 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. 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 a7R III is exceptionally capable as a video camera, offering 4K2 (3840×2160 pixels) video recording across the full width of the full-frame image sensor. When shooting in Super 35mm format, the camera uses full pixel readout without pixel binning to collect 5K (15-megapixels) of information, oversampling 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 TVâs to playback beautiful, true-to-life 4K HDR imagery. The a7R III can also record Full HD at 120 fps at up to 100 Mbps*, allowing footage to be reviewed and eventually edited into 4x or 5x slow motion13 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 â 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, a first in palm-sized cameras, the a7R 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.
16-bit processing and 14-bit RAW15 output for natural gradations
Both compressed and uncompressed 14-bit RAW15 format are supported. The 14-bit digital signal from the image sensorâs analogue 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 RAW 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 RAW output available even when shooting in silent or continuous mode15.
Simple connectivity to smartphones via Wi-FiÂ®/NFC.
Thanks to built-in Wi-FiÂ®, you can easily connect to a compatible iOS or Android™ smartphone or tablet with the free PlayMemories Mobile App. From there you can control your camera, preview and frame using your mobile device and trigger the camera shutter or movie button.

FTPS (File Transfer Protocol over SSL/TLS) is supported, allowing SSL or TLS data encryption for maximum security. NFC™ (Near Field Communication) provides âone-touch connectionâ convenience to Android™ smartphones and tablets with NFC. Simply touch devices to connect. Setting up your mobile device is as simple as downloading a free PlayMemories Mobile app (www.sony.net/pmm/).
Quad-VGA OLED Tru-Finder with 120 fps* refresh rate
The a7R III boasts a high-luminance 3,69K-dot Quad-VGA OLED Tru-Finder which reproduces the finest details, and incorporates legendary ZEISS T* coating to greatly reduces reflections, while the double-sided aspherical element achieves 0.78x magnification with outstanding corner-to- corner clarity. A menu setting allows viewfinder and monitor display quality to be set to âSTDâ or âHiâ. The âHiâ mode takes advantage of the large amount of data read from the 42.4 effective megapixel sensor to provide extra fine viewfinder and monitor displays with minimal moirÃ© and jaggies, providing finer detail and a more natural overall view while shooting. It also has a customizable frame rate, with options of either 60 fps or 120 fps14 to best match the action. Thereâs even a fluorine coating on the outermost viewfinder lens that repels fingerprints, dust, water, oil, and dirt.
3-inch 1,440K-dot tiltable LCD screen with touch AF
The tiltable 3-inch (1,440k dots) Xtra Fine LCD™ Display makes it easy to photograph over crowds, or objects close to the ground or maybe you just want to get a different perspective. The screen can swivel up approx. 107Â° and down approx. 41Â° and features a convenient touch AF function for fast intuitive focus. The large display delivers brilliant-quality still images and movies thanks to WhiteMagic™ technology that nearly doubles the brightness of the display through a unique RGBW pixel structure for easier checking of the focus and image details.
Touch AF function
Focusing doesnât get any more intuitive than this. With Touch Focus you can simply touch the LCD screen to specify the desired focus point. Even subjects near the edges of the frame can be instantly selected without having to reframe or manually shift the focus point. Double-tap any point on the monitor for a magnified view of that area when focusing manually. Touch AF allows smooth focus point changes when shooting movies too.
Eye AF automatically detects and focuses on the subjectâs eye. It has been notably improved in the a7R III, providing approximately twice as effective compared to the a7R II, even when shooting a moving subject in continuous AF mode. Face detection has also been updated for higher reliability when the subject is looking away from the camera, when the face is in partial darkness, and other challenging situations.
Fast focus with A-mount lenses12
The focal plane phase-detection AF system does its job even when an SSM or SAM A-mount lens is mounted via the optional LA-EA3 mount adaptor12. 399-point focal plane phase-detection AF provides wide-area coverage and fast response for A-mount lenses as well as E-mount types, offering high tracking performance for an extensive lineup of lenses.
Long-lasting Z battery
The high-capacity NP-FZ100 Rechargeable Battery has approximately 2.2x the capacity of the NP-FW50 W-series battery for more than double the stamina of the W series as used in the a7R II. The optional VG-C3EM vertical grip houses two batteries and when you need serious stamina for long sessions thereâs the NPA-MQZ1K Multi Battery Adaptor Kit that can hold up to four batteries. The NP-FZ100 also supports InfoLITHIUMÂ® technology, which makes it possible to view the remaining battery power as both a percentage display and five step icon on the cameraâs LCD screen.
Robust magnesium alloy body w/ dust and moisture resistant design9
The a7R III body construction features a lightweight, high-rigidity magnesium alloy for the internal frame as well as the top, front, and rear covers. The grip area has also been reinforced with an integrated magnesium alloy grip and front cover. The number of screws securing the lens mount has been increased to six in order to maximize rigidity and durability even when using heavy telephoto lenses. Sealing is provided throughout the body to minimize dust and moisture ingress, allowing it to function reliably in challenging environments9. All major buttons and dials are provided with seals, while media and jack covers and enclosure edges feature tongue-and-groove joints for double protection. Maximum dust and moisture resistance is maintained at lens, vertical grip, and flash unit joints too, providing excellent system reliability.
Rating and protect functions
Rating and protect functions facilitate on-location sorting Star ratings (1 to 5 stars) can be applied to still images right from the camera controls. The same ratings are maintained when the images are imported into PlayMemories Home or Imaging Edge software running on a PC. The rating function can be assigned to a custom button so that ratings can be applied via the review playback display. There is also a protect function that can prevent accidental erasure of images. The protect function can be assigned to a custom button (C3 is the default) so that images can be quickly protected during review. Ratings and protection can be applied via the review playback display on location or while traveling to save time.
My Menu, customizable interface and buttons, plus back focus button
Make it your own with easy button customization. A new My Menu feature allows up to 30 menu items to be registered for instant recall when needed. The registered items can be arranged in any convenient order, and unused items can be erased as required. The primary menus have also been reorganized for smoother search and operation. In addition, You can assign any of 72 functions to any of 11 customizable buttons as you like. This makes operation more intuitive, quick and easy, and is extra-convenient for accessing such functions as starting and stopping of movie recording and switching between viewfinder and monitor.
AF-ON button (back focus button)
The a7R III has several new and updated focus functions that support faster, easier focusing in a variety of situations including the AF-ON button (back focus button) which activates autofocus when pressed while shooting stills or movies.
The camera features a multi-selector joystick on the back of the camera, allowing shooters to easily shift focus within the frame by pressing the multi-selector in any direction up, down, left or right when shooting in Zone, Flexible Spot or Expanded Flexible Spot focus area modes.
Anti-dust system and coating
To keep your photos blemish-free, a special anti-static coating on the surface of the optical filter suppresses the attachment of both dry and moist dust particles when changing lenses. An anti-dust mechanism also vibrates at high speed when you select Cleaning Mode, to remove any particles adhering to the filter.
Meticulously crafted controls
Controls are refined for intuitive operation and immediate adjustment even while looking through the viewfinder. The Î±9 features front and rear dials for easier, more efficient handling and turning. A mode dial locking mechanism prevents inadvertent changes of shooting mode at all times and a stacked independently operable dials allow fast selection of drive and focus modes. Quickly select the single or continuous drive mode, or the single AF or continuous AF focus mode, for example, without having to scroll through menus. Both dials are lockable, preventing unwanted mode changes during use.
Improved flash compatibility and flash Sync terminal
There is a sync terminal enabling external flash units and cables to be connected directly for convenient flash sync. Whatâs more, release time lag has been minimized for smooth, responsive flash photography. Continuous flash shooting at up to 10 fps125 offers advanced capture capability. Slow sync and rear curtain sync*26 can be selected when shooting with wireless off-camera flash for even further enhanced versatility.
If there is fluorescent or artificial lighting present in a shooting environment, users can activate the Anti-flicker16 function to allow the a7R III to automatically detect frequency of the lighting and time the shutter to minimize its effect on images being captured. This minimizes any exposure or color anomalies that can sometimes occur at the top and bottom of images shot at high shutter speeds.
