Product Information

What Stands out

  • Sensor Size: Full Frame, Exmor R CMOS Sensor
  • Weight: 650g
  • Megapixels: as 24.2MP
  • Video: 4K

Back-illuminated 24.2MP full-frame sensor

The 35mm full-frame Exmor R CMOS image sensor features 24.2-megapixel resolution, back illumination, and gapless on-chip lens design for extraordinary sensitivity and dynamic range. Two times faster data readout speed is achieved through copper wires and front-end LSI.

Entirely enhanced image processing system

A combination of new-generation image processing system and a new sensor achieves an up to 1.5-stop improvement in image quality. A wide ISO sensitivity range of up to ISO 51200 is standard, and approx. up to 15-stop dynamic range at low sensitivity settings is realised. Upgraded Detail Reproduction and Area-specific Noise Reduction join to suppress noise and maintain a sense of high overall resolution. Colour reproduction, especially of skin and nature scenes, has also been dramatically improved. The α7 III also supports 14-bit RAW output even during silent shooting/continuous shooting.

Wider, faster, more steadfast AF performance

An evolved image processing system and α9 camera AF algorithms optimised for the α7 III improve AF speed, precision, and tracking performance. 693 phase-detection AF points and 425 contrast-detection AF points provide high-density wide-area coverage. AF speed improved by up to twice and more precise AF tracking performance let you capture and maintain focus on a quickly moving subject in unpredictable motion. The α7 III also autofocuses reliably down to EV-3 brightness.

Focal-plane phase-detection AF supports A-mount lenses

Phase-detection AF can operate even when an A-mount lens is mounted to the α7 III via an LA-EA3 adaptor. The 693-point focal-plane phase-detection AF system provides wide-area coverage, fast response, and high-performance tracking.

AF-ON button and multi-selector

The new AF-ON button activates autofocus without any half-press-shutter-button focus sequence, so you can concentrate better on exactly when to release the shutter and capture the moment instantly. A multi-selector lets you shift the point of focus quickly and efficiently. You can select and shift the point of focus intuitively, so you won’t miss great chances to shoot moving subjects.

Always keep the eye in focus

Eye AF newly supports AF-C mode with greater precision that dramatically enhances portrait shooting, plus higher AF speed that makes it easier to shoot a portrait of a moving subject, even if the subject looks down and away from the camera, or is backlit with face in partial darkness. The α7 III supports Eye AF for A-mount lenses mounted via an adaptor.

Comprehensive AF convenience

AF tracking sensitivity when shooting stills is adjustable in five steps for subjects that move outside of the focus area. Autofocus areas and points remain the same or change when switching between horizontal and vertical orientations, depending on the shooting situation. AF area registration allows frequently used focus point settings to be memorised and assigned to custom buttons for fast, convenient recall at a touch whenever needed.

Enhanced operability for continuous shooting

Images captured in continuous shooting mode can be displayed as a group, and such groups can be deleted or protected in one quick operation. Furthermore, with higher burst capacity and UHS-II media compatibility, the camera significantly streamlines the operation of writing data to memory cards. The Fn button and menu button can be operated to change settings immediately after continuous shooting, while data writing is in progress.

Up to 10 fps with AF/AE tracking

With new shutter charge unit and image processing system refinements, the α7 III can shoot continuously at up to 10 fps with AF/AE tracking21 (up to 8 fps with minimal display lag in live-view continuous shooting mode) for easy, stable shooting of even intensely active subjects. Up to approximately 177 JPEG images (standard) in full resolution, 89 compressed RAW images, or 40 uncompressed RAW images can be captured in one continuous burst. An electronic shutter allows silent, vibration-free shooting of wildlife and other sensitive situations when even slight noise can mean missing an ideal shot.

Anti-flicker shooting

Flicker from fluorescent and other artificial lighting is automatically detected and shutter action is timed to minimise the flicker’s effect on still images. This suppresses exposure and colour anomalies at the top and bottom of images shot at high shutter speeds, as well as exposure and colour inconsistency between continuous shots, so you can take images indoors with more confidence.

Supports a wide range of needs in HDR movie production

Supporting a wide range of HDR movie production needs, the α7 III offers S-Log3 as well as S-Log2 gamma curves, for great flexibility to fine-tune images as desired through colour grading operation in post-production, and a new HLG (Hybrid Log-Gamma) picture profile for instant HDR workflow. However, colour grading is not required to enjoy instant playback of high-quality, true-to-life images with no blocked shadows or blown highlights on an HDR (HLG) compatible TV.

Clear, natural, realistic 4K movies25

High-resolution full-frame 4K movies with full-pixel readout without pixel binning that condenses approximately 2.4 times the amount of data required for 4K movies (QFHD: 3840 x 2160) results in minimal moiré and jaggies. Advanced image processing makes it possible to record full-frame 4K movies with outstanding image quality in the mid-to-high ISO range, so you make the most of the 4K movie format’s unique potential in every shot. Super 35mm can also be selected, instead of full-frame mode, as needed.

Rating function convenient for on-location sorting

Ratings from 1 to 5 stars can be applied to still images and maintained as the images are imported into PlayMemories Home or the new Imaging Edge software suite from Sony running on a PC. This function and a protect function to prevent accidental image deletion can each be assigned to a custom button (C3 by default for protect). Ratings and protection can be applied via review playback display and continuous groups can be reviewed, protected, and deleted while you’re on location or traveling.

My Menu and new menu interface

My Menu lets you register and arrange up to 30 menu items in order of frequency of use for instant recall, and unused items can be erased, as needed. A custom menu can be created to suit particular shooting needs. The α7 III has primary menus reorganised for easier searching, with group names and page numbers at the top of the displays.

Improved Fast Hybrid AF for movie recording

An efficient combination of focal-plane phase-detection AF and contrast-detection AF accurately locks onto even fast-moving subjects, then tracks them smoothly during movie recording. AF coverage for movies extends across an area almost as wide as the AF coverage area for still images, so once the high-density AF system locks onto a movie subject, the camera continues to track it steadily and tenaciously. Three AF drive speed settings give you freedom to use slow focus effects when shooting movie scenes.

Touch screen LCD for easy instant focus operation

A 3.0-type 922K-dot LCD screen offers touch screen operation and bright, clear, finely detailed views even outdoors. Use Touch Focus to focus instantly on a point that you touch on the screen and Touch Pad to drag the focus frame with a fingertip on the LCD as you monitor the shot through the viewfinder. This LCD tilts up by as much as 107°, and down by as much as 41° for flexible, convenient camera holding and shot monitoring.

Promptly changeable customisation

Camera setups can be registered (up to two in the camera and four on a memory card) for quick access via mode dial. Up to 81 functions can be assigned to 11 custom keys, and even sets of customised functions can be assigned for stills, movies, and playback. Recall Custom Setting During Hold function is convenient for temporary recall of shooting settings assigned to custom buttons while such a button is held.

High-resolution, high-contrast XGA OLED Tru-Finder

Providing high resolution and contrast, plus the excellent gradation and colour reproduction that are advantages of OLED viewfinders, this approximately 2359K-dot XGA OLED Tru-Finder faithfully depicts images with clear corner-to-corner visibility. Magnification is 0.78x (approx. 38.5° diagonal FOV). ZEISS T* coating greatly reduces obtrusive lens reflection on the ocular lens. Startup is approximately 40% faster than with the α7 II when the camera is switched on. Furthermore, view mode can be set to “High” to provide finer and more natural details by taking maximum advantage of the data read from the 24.2 effective megapixel sensor.
