Advances have also been made in Sony's Detail Reproduction Technology and Area specific Noise Reduction features, reducing noise by as much as a full stop in the mid sensitivity range. A sublime blend of high resolution and low noise is ensured over a wide sensitivity range, for outstanding image quality and color accuracy that are ideal for portraits and landscape photography.
|EXMOR R CMOS SENSOR
||BIONZ X IMAGEPROCESSING ENGINE
Standard 100 - 32000 ISO expandable up to 102400
The standard ISO range has been extended to ISO 100 - 32000, expandable to ISO 50 at the low end and ISO 102400 at the high end for wide coverage that can capture low-light scenes with high quality and low noise.
16-bit processing and 14-bit RAW output
The digital output from the image sensor's AD converter is processed in 16-bit form by the front-end LSI and BIONZ X processor before being output as compressed or uncompressed 14-bit RAW files. The result is smoother, more natural gradations that contribute to higher overall image quality. The enhanced image processing system makes 14-bit RAW output available even when shooting in silent or continuous mode.
UNPRECEDENTED AF PERFORMANCE
Updated algorithms enhance AF response
Evolved image processing plus AF algorithms from the a9 refined and optimized for the a7R III provide significant improvements in AF speed, precision, and tracking performance. Even the wildest motion can be tracked reliably.
399 phase-detection + 425 contrast AF points
399 focal plane phase-detection AF points cover approximately 68% of the image area in the horizontal and vertical directions, complementing 425 contrast AF points for consistently reliable focus.

Up to 2x AF speed
Enhanced Fast Hybrid AF System performance achieves low-light AF response that is up to twice as fast as the a7R II. Focus is fast and reliable even in dim lighting.
Subject tracking performance approximately doubled
Tracking performance during continuous shooting has been improved by approximately 2x. Complex, unpredictable motion is reliably tracked with greater precision than ever before.
Focal plane phase-detection AF with A-mount lenses
Focal plane phase-detection AF also functions with A-mount lenses mounted via the LA-EA3 adapter, providing wide-area coverage, fast response, and high tracking performance. Eye AF is now supported with A-mount lenses.
Reliable AF down to EV-3 brightness
Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-3 (ISO 100 equivalent, F2.0 lens) in the AF-S mode. AF is more precise and reliable in dark scenes.
AUTOMATIC, INSTANT EYE FOCUS
Doubled Eye AF performance
Eye AF automatically detects and focuses on the subject's eye. Notable improvements in detection precision and speed in the a7R III result in approximately doubled* tracking performance when shooting moving portrait subjects. Eye focus is fast and accurate even if the subject is distant, looking away from the camera, backlit, or in other situations that would challenge previous systems. Eye AF is also supported for A-mount lenses mounted via an adapter.

IN-BODY IMAGE STABILIZATION
5-axis optical in-body image stabilization for a 5.5-step exposure advantage
A new precision stabilization unit and gyro sensors work with optimized image stabilization algorithms to achieve a 5.5-step shutter speed advantage. Camera shake is effectively compensated for in 5 axes, and stabilization is effective for movies as well as stills. The viewfinder image is stabilized too, making it easier to frame and focus. Effective stabilization is achieved with a wide range of lenses, including non-stabilized E-mount lenses, and A-mount lenses mounted via an adapter.
Pitch and yaw compensation
Compensation for commonly experienced pitch and yaw shake at long focal lengths.
Horizontal and vertical shift compensation
Compensation for X and Y-axis shift shake at high magnification (during macro photography, etc.).
Compensation for roll shake on the Z-axis during long exposures. Most in-lens systems for interchangeable lens cameras cannot compensate for roll shake.
HIGH-SPEED CONTINUOUS SHOOTING
Up to 10 fps continuous shooting with AF/AE tracking
Continuous shooting at up to 10 fps with accurate AF/AE tracking makes it possible to capture moving subjects in their most photogenic moments while taking full advantage of the camera's 42.4 megapixel resolution and 14-bit output. The image files produced contain ample data for flexible trimming and retouching without losing image quality. It is also possible to shoot continuously at up to 8 fps in live view mode, with minimal viewfinder/monitor display lag.
Silent continuous shooting
Silent, vibration-free shooting at up to 10 fps with AF/AE tracking and no cropping is also available when shooting in silent mode. Silent shooting is critical for wildlife photography where even the slightest shutter noise can mean missing the moment.
MORE CONTINUOUS SHOOTING SUPPORT
Up to 76 images per burst
A larger buffer memory, increased overall system speed, UHS-II support, and other refinements allow up to 76 JPEG or compressed RAW images, or up to 28 uncompressed RAW images to be captured in one continuous burst.
Dual media slots, UHS-II support
Separate media slots for SD card (UHS-II compatible) and SD/MS card allow data to be simultaneously or sequentially recorded to two cards (Auto Switch Media), or separate cards can be assigned to save RAW and JPEG files, or stills and movies. Data can also be copied between media cards.
Improved operability while writing to memory card
The Fn menu can be accessed and edited immediately after continuous shooting while data writing is in progress, as can the menus and parameters. It is also possible to immediately access the playback display, with the number of still images remaining to be written shown during playback.
Rating and protect functions facilitate on-location sorting
Ratings of from 1 to 5 stars can be applied to still images right from the camera controls. The rating and protect functions can be set via assigned custom buttons while viewing the review playback display on location or while traveling to save time.
Display continuous shooting group
Images shot in continuous mode can be reviewed as groups, and the play index display has been significantly improved. Continuous groups can be deleted or protected in one quick operation to save time on location.

LIFELIKE DETAIL, TEXTURE, COLOR, AND ATMOSPHERE
Superior resolution from 42.4 megapixel RGB information
This new feature takes advantage of the advanced in-body image stabilization system control capability available in the a7R III, precisely shifting the sensor in 1-pixel increments to capture four pixel-shifted images containing a total of approximately 169.6 million pixels that are later composited using a computer to achieve overwhelming subjective resolution in a single image. Still images are captured with true-to life details, texture, and color, with minimal moiré and color artifacts. Even the atmosphere of the subject and surroundings are reproduced with breathtaking fidelity, making Pixel Shift Multi Shooting an ideal technology for archival images of art, architecture, and more.
| NORMAL SINGLE IMAGE
|| WITH PIXEL SHIFT MULTI SHOOTING
The Pixel Shift Multi Shooting principle
"Standard" and "High" quality settings are available for the viewfinder and monitor. "High" takes advantage of the large amount of data read from the 42.4 effective megapixel sensor to provide extra fine viewfinder and monitor displays for a more natural view.
HIGH-RESOLTION, WIDE-DYNAMIC-RANGE 4K
4K movies from 5K (15-megapixel) data
Full pixel readout in the Super 35 mode, without the need for pixel binning, makes it possible to condense 5K (15-megapixel) data into high resolution, extraordinarily beautiful 4K movies with minimal moiré and jaggies. Advanced image processing also allows full-frame 4K movie recording with dramatically improved image quality at mid to high sensitivities. Super 35mm or full-frame recording can be selected as required.
WIDE DYNAMIC RANGE
Broad support for HDR content creation
Sony's S-Log gamma curve provides extra flexibility to achieve a "look" that best serves your artistic vision during post-production color grading, while a newly added HLG (Hybrid Log-Gamma) picture profile supports instant HDR production without the need for color grading. Extra care has been taken to ensure that a wide range of HDR content creation requirements are fully supported.
HLG (Hybrid Log-Gamma) support for instant HDR workflow
Movies recorded using the HLG profile will appear true-to-life with no blocked shadows or blown highlights when played back on an HDR (HLG) compatible TV, without the need for color grading. The BT.2020 color space is supported, providing a wider color gamut.
S-Log3 for wide 14-stop dynamic range
In addition to S-Log2, S-Log3 is available for better gradation from shadows to mid-tones (18% gray) and a wide dynamic range of up to 14 stops for movies. A new color SGamut3 color space that is a refined version of S-Gamut is also provided.
|S-GAMUT3.CINE / S-LOG3
COMPREHENSIVE MOVIEMAKING CONTROL
Improved Fast Hybrid AF for movies
Fast Hybrid AF performance during movie recording has been refined, providing a wide AF area that is similar to that provided for still images. AF now accurately locks onto movie subjects over a wider area.
Slow and quick motion
Frame rates from 1 fps to 120 fps can be selected in eight steps for up to 60x quick motion and 5x slow motion while recording with full-HD quality.
Enhanced Zebra function
This function simplifies exposure monitoring, especially when shooting with Log gamma. A new minimum brightness level setting helps to avoid blown out highlights.
4K movies and lower-resolution proxy movies can be recorded simultaneously. The smaller proxy files are ideal for quick previewing or pre-editing that can reduce the time required for final 4K editing.
High-quality stills can be extracted from movies and stored separately: 8 megapixel stills from 4K movies, and 2 megapixel stills from full-HD movies.
Auto Power Off Temperature
This function sets the temperature at which the camera will automatically shut off. "High" allows longer movie recording times when the camera is mounted on a tripod.
Other movie features
Picture profiles, Clean HDMI, Time Code/User Bit, REC control, Gamma Display Assist, and other details provide comprehensive support for advanced video work flows.
3.69 million dot Quad-VGA OLED Tru-Finder
This high-resolution Quad-VGA OLED Tru-Finder has approximately 3.69 million dots for fine detail and high contrast for accurate black reproduction. High luminance brings viewfinder brightness closer to that of the actual scene. The high quality of the viewfinder image and features like focus magnification make it easier to achieve perfect focus with just about any subject in any situation.
|QUAD-VGA VIEWFINDER ("HI" QUALITY MIDE)
||CONVENTIOINAL XGA VIEWFINDER
High quality mode
In a "normal" 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 Shooting, however, composites four pixel-shifted images so that each of the sensor's 42.4 million effective pixels can represent red, green, and blue values simultaneously. Extra interpolation becomes unnecessary so the data from the sensor can be directly synthesized to recreate the final colors. The result is unprecedented reproduction accuracy and detail for true-to-life textures. Images shot using this feature can be processed using the dedicated PC software from Sony running on a personal computer.
AF in Focus Magnifier
By magnifying the selected focus area while using auto focus to shoot stills this function makes it easier to achieve perfect focus, especially for macro photography and other critical applications.
The evolved BIONZ X processing engine improves the accuracy of "peaking" display that highlights in-focus areas when focusing manually, making it easier to achieve precise focus.
EFFICIENT FOCUS CONTROL
Press the AF-ON button to activate auto focus when shooting stills or movies. This makes it possible to release the shutter instantly to capture fleeting moments without having to go through the normal half-press focus sequence.
The multi-selector provides a fast, efficient way to shift focus points. Simply press the up, down, left, or right button when using the Zone, Flexible Spot, or Expand Flexible Spot focus area mode.
3.0 type 1.44 million dot tilting LCD monitor
This 3.0 type LCD monitor with 1.44 million dots features high resolution for detailed viewing. WhiteMagic technology is included to ensure that LCD viewing is bright and clear even in outdoor conditions. The monitor tilts upwards by a maximum of 107°, and downwards by a maximum of 41° for flexible hold and framing.
| LOW ANGLE TILT
|| HIGH ANGLE TILT
Simply touch the monitor screen to specify the desired focus point for stills or movies. Even subjects near the frame edges can be instantly selected without having to reframe or manually shift the focus point. Double-tap any point for a magnified view of that area when focusing manually.
Touchpad focus point control
The monitor touchpad function allows the focus frame to be dragged to any desired point with a fingertip while viewing through the viewfinder. Relative and absolute modes are available, and nine area patterns provide easy operation when viewing with either eye, and when positioning with either hand.
CUSTOMIZABLE FUNCTIONS FOR SMOOTH FOCUS OPERATION
Switch Vertical and Horizontal AF Area
It is possible to use separate or identical focus areas and points for horizontal and vertical camera orientations, reducing the need to readjust focus when shooting subjects that requires frequent camera orientation changes.
AF tracking sensitivity
The sensitivity with which auto focus will follow subjects that move outside the focus area can be adjusted in 5 steps when shooting stills. Higher sensitivity is best for subjects at varying distances, while lower sensitivities can keep focus on a subject that is briefly obscured by other objects.
AF Area Registration
Frequently used focus point settings can be memorized and instantly recalled via custom button assignments. Focus area mode settings can also be memorized and recalled as required for fast, convenient operation.
Recall Custom Setting During Hold
Memorized settings (exposure, focus settings, drive mode, etc.) can be assigned to custom buttons for temporary recall while the button is held, providing a convenient way to quickly make temporary setting changes.
CUSTOMIZABLE INTERFACE FUNCTIONS

Custom button assignments
Custom button assignments allow the camera interface to be customized for individual shooting preferences. Eleven buttons can be reassigned to select functions you choose, and separate functions can be assigned for the still, movie, and playback modes.
||CUSTOM BUTTON ASSIGNMENTS
Customizable front/rear dials and release button
The control direction of the front and rear dials can be set via the menus. It is also possible to assign the large, accessible shutter button to start and stop movie recording, rather than using the MOVIE button.
Instant mode dial recall of memorized camera setups
Camera setups, including modes and camera settings, can be registered in memory for instant recall via the mode dial: up to three in the camera, and four on a memory card. Memory card setups can also be loaded into a separate a7R III body.
FLEXIBLE AUTO EXPOSURE AND AUTO WHITE BALANCE
1200-segment live view exposure analysis enhances stability
The live view image is divided into 1,200 segments for detailed analysis of subject color and lighting. The use of focus information to ensure consistent AE control is another innovation that can reduce variations in image brightness in varying situations.
Additional modes expand metering versatility
A new Highlight mode detects the brightest area in the frame to avoid blown highlights, and an Entire Screen Average mode can provide stable auto exposure through composition changes.
Versatile spot metering
When the Focus Area parameter is set to Flexible Spot or Expand Flexible Spot the metering spot location can be linked to the focus area so that the optimum metering point is maintained automatically. Two spot sizes are available to match a wide range of subjects.
Flicker from fluorescent lights and other artificial lighting can ruin still images if it and the shutter timing are out of sync. The a7R III automatically detects flicker and adjusts shutter timing to eliminate its effects.
Exposure standard adjustment
The standard exposure value can be adjusted from -1 to +1 stop in 1/6 stop increments. This setting can be made separately for each metering mode.
ISO AUTO Min. shutter speed
This function sets the shutter speed above which ISO sensitivity will begin to change when the camera mode is set to "P" or "A" and "ISO AUTO" is selected. It can be used to minimize subject blur when shooting moving subjects.
Priority Set in AWB
