Back-illuminated 42.4 MP full-frame sensor
The 35 mm full-frame Exmor R CMOS image sensor features 42.4-megapixel resolution, back illumination and gapless on-chip lens design for extraordinary sensitivity and dynamic range, anti-reflection (AR) coating on sensor seal glass and other innovations that unleash the sensor’s power to make images look realistic.
Enhanced image processing engine
The latest front-end LSI makes data readout from the image sensor approximately two times faster and the BIONZ X image processor is now about 1.8 times faster. Enhanced image processing realises lower noise and further extended dynamic range across a wide sensitivity range of up to ISO 32000.
Eye Auto Focus
Eye AF’s enhanced precision, plus two times greater AF speed and AF tracking performance, further assist you to easily shoot a portrait of a moving subject using AF-C even during continuous shooting, and even if the subject looks down and away from the camera or is backlit with face in partial darkness.
Up to 10fps
With new shutter unit and image processing system refinements, the A7R III can shoot continuously at up to 10fps with AF/AE tracking (up to 8fps with minimal display lag in live-view continuous shooting mode) for easy, stable shooting of even intensely active subjects.
Up to 76 images in continuous shooting
Greater buffer memory, system speed and UHS-II support allow the A7R III to capture up to approx. 28 uncompressed RAW, or 76 compressed RAW or JPEG images, in a continuous burst at 10fps. Fn menu/menu display access, setting changes and review playback can occur during data writing.
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.
This approximately 3.69-million-dot Quad-VGA OLED Tru-Finder provides accurate detail, contrast and black reproduction, while maintaining natural image brightness. High-quality mode, suitable for fine focus adjustment, takes full advantage of rich image data from the image sensor to display more natural high-precision images with minimal moiré and jagginess.
Dual slots with UHS-II compatibility
This camera provides two media slots for SD card (UHS-II-compatible for fast data writing) and SD/MS card respectively. Two cards in the slots can be used to simultaneously record or relay record data, separate RAW data from JPEG data, or stills from movies, and copy data from one card to the other. The memory card cover is lockable to prevent it from being opened unintentionally.
Touch screen LCD for intuitive focus operations
A 7.5 cm (3.0-type) LCD touch screen with 1.44 million dots makes focus operation intuitive and instant. You can simply touch the monitor screen to specify a desired focus point with Touch Focus. Also, the Touch Pad function lets you drag the focus frame to another point with a fingertip on the LCD screen as you monitor the shot through the viewfinder.
Smooth PC tethering via USB 3.1 Gen 1 port
A USB Type-C™ port supporting fast USB 3.1 Gen 1 facilitates high-speed PC Remote transfer of large RAW data files, so you can quickly review images on a PC and continue shooting without delay. Also, a setting to transfer only JPEG files to PC lets you check images via PC even more quickly after continuous shooting because the camera doesn’t have to send big volumes of RAW data.
Clear, natural, realistic 4K movies
For high-resolution 4K movies with minimal moiré and jaggies, Super 35 mm mode with full-pixel readout without pixel binning condenses approximately 1.8 times35 the amount of data required for 4K movies (QFHD: 3840 x 2160). Advanced image processing makes it possible to record full-frame 4K movies with dramatically improved image quality in the mid-to-high ISO range.
HDR movie production
Recorded movies played back on an HDR (HLG) compatible TV need no colour grading to appear true-to-life, with no blocked shadows or blown highlights. Supporting a wide range of HDR movie production needs, the A7R III offers S-Log3 as well as S-Log2 gamma curves, for more flexibility to express images through grading operation in post-production.
One-touch remote and One-touch sharing
One-touch remote can turn a smartphone or tablet into a viewfinder/remote control. One-touch sharing transfers photos / videos to your device for SNS sharing. Just install the PlayMemories Mobile app via Wi-Fi to your NFC-enabled Android device, and then touch the device to the camera to connect them. If you don’t have NFC, use QR code compatibility to pair the devices.
Supports 14-bit uncompressed RAW format
The A7R III supports 14-bit RAW output even during silent shooting/continuous shooting.14-bit RAW format output contains rich tonal information from highlights to shadows and is available even when shooting in silent or continuous mode.
This camera allows silent shooting at up to 10 fps13 with AF/AE tracking. Silence is critical for shooting wildlife, when even slight noise can mean missing a chance at an ideal shot.
