Back-illuminated 24.2MP full-frame sensor
The 35 mm 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. Wider, faster, more steadfast AF performance
An evolved image processing system and a9 camera AF algorithms optimized for the a7 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 up to twice as fast and more precise AF tracking performance let you capture and maintain focus on a quickly moving subject in unpredictable motion. The a7 III also autofocuses reliably down to EV-3 brightness. 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 a7 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 memorized 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. 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. Clear, natural, realistic 4K movies
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 moir 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 formats unique potential in every shot. Super 35 mm can also be selected, instead of full-frame mode, as needed. Versatile movie recording functions
The a7 III provides a wide array of functions to facilitate workflows of professional videographers, including clean HDMI output, time code / user bits (TC/UB), rec. control, marker display/setting, zebra function, Slow and Quick Motion, simultaneous proxy movie recording, extraction and separate storage of a still from a movie, and Gamma Display Assist function, among others. 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 a7 III has primary menus reorganized for easier searching, with group names and page numbers at the top of the displays. Promptly changeable customization
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 customized 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
