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.
Flicker from fluorescent and other artificial lighting is automatically detected and shutter action is timed to minimize the flicker's effect on still images. This suppresses exposure and color anomalies at the top and bottom of images shot at high shutter speeds, as well as exposure and color inconsistency between continuous shots, so you can take images indoors with more confidence.
Versatile movie recording functions
The α7 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.
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 color grading operation in post-production , and a new HLG (Hybrid Log-Gamma) picture profile for instant HDR workflow. However, color 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 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 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 35 mm 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 reorganized 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.
