Newly developed 24.2MP BSI Full-frame Image Sensor
The newly developed 24.2MP back-illuminated Exmor R™ CMOS image sensor is paired with a front-end LSI that effectively doubles the readout speed of the image sensor, as well as an updated BIONZ X™ processing-engine that boosts processing speed by approximately 1.8 times compared to the α7 II.
Evolutionary leap in image processing power
The a7 III features a new front-end LSI that effectively doubles* the readout speed of the image sensor, as well as an updated BIONZ X™ processing-engine that boosts processing speed by approximately 1.8 times compared to the a7 II.
Up to 10fps1 with Silent5 or Mechanical Shutter
The a7 III is equipped with a refined image processing system that allows it to capture full 24.2MP images at up to 10 fps1 with continuous and accurate AF/AE (autofocus and auto exposure) tracking for up to 177 Standard JPEG images, 89 compressed RAW images or 40 uncompressed RAW images.
Incredible hybrid autofocus system
The a7 III features a world class autofocus system comprised of 693 focal-plane phase-detection AF points that cover approximately 93% of the image area, 425 contrast AF points and reliable Eye-AF. When combined, both contrast and phase detection AF points form the 4D FOCUS ™ hybrid AF system for wide, fast, reliable AF that locks on and stays locked on.
5-step6, 5-axis in-body image stabilization
The 5-axis in-body SteadyShot™ image stabilization system has been fine-tuned to support high-resolution shooting capacity, resulting in an image stabilization system at 5-step6 shutter speed advantage. Camera shake is effectively compensated on 5 axes: pitch and yaw that have the largest overall impact on image quality; X and Y shift that is most apparent at high magnification, and roll that can ruin night shots and movies.
Secure and versatile dual SD media slots
Two SD media card slots are provided for still and movie storage (one slot for SD cards or Memory Stick) with the lower card slot being UHS-II compatible for fast write speed. Still or movie data can be simultaneously recorded to both cards for backup, or RAW4 images can be recorded to one card while JPEG images are recorded to the other.
High Quality 4K2 HDR3 for the Video Professionals
The a7 III is exceptionally capable as a video camera, offering 4K2 (3840×2160 pixels) video recording across the full width of the full-frame image sensor. In video mode, the a7 III uses full pixel readout without pixel binning to collect about 2.4x the amount of data required for 4K movies, and then oversamples it to produce high quality 4K footage with exceptional detail and depth.
The detail of 4K2, the beauty of HDR3
4K2 HDR3 (High Dynamic Range) astonishes viewers with visual depth and impact that are less like conventional movies and television – and more like real life. With the ability to reproduce images from deep shadows to piercing highlights, 4K High Dynamic Range (HDR) is astonishing. With Instant HDR, the a7 III empowers you to capture High Dynamic Range without complex post production.
Long-lasting Z battery
The high-capacity NP-FZ100 Rechargeable Battery has approximately 2.2x the capacity of the NP-FW50 W-series battery giving the a7 III the longest7 rated battery life of any Mirrorless camera at 710 shots8 per charge .
16-bit processing and 14-bit RAW4 output for natural gradations
Both compressed and uncompressed 14-bit RAW4 format are supported. The 14-bit digital signal from the image sensor’s analog to digital (AD) converter is processed in 16-bit form by the front-end LSI and BIONZ X™ image processor before being output as 14-bit RAW4 data.
High contrast 2.36-million dot OLED EVF
The a7 III boasts a high-luminance 2.359 million dots EVF (XGA OLED) Tru-Finder™ which reproduces the finest details, and incorporates legendary ZEISS T* coating to greatly reduce reflections, while the double-sided aspherical element achieves 0.78x magnification with outstanding corner-to- corner clarity.
922K-dot (approx.) 3” (3.0 type) tilting LCD monitor
This large tiltable 3” (3.0 type) LCD monitor features approximately 922K dots* for high resolution and detailed viewing. The monitor not only supports touch operation, but tilts upwards by a maximum of 107° and downwards by a maximum of 41° for flexible hold and framing.
Touch AF function
Focusing doesn’t get any more intuitive than this. With Touch Focus you can simply touch the LCD screen to specify the desired focus point. Even subjects near the edges of the frame can be instantly selected without having to reframe or manually shift the focus point.
Enhanced Eye-AF
Eye AF automatically detects and focuses on the subject’s eye. It has been notably improved in the a7 III, even when shooting a moving subject in continuous AF mode. Face detection has also been updated for higher reliability when the subject is looking away from the camera, when the face is in partial darkness, and other challenging situations.
Robust magnesium alloy body w/ dust and moisture resistant design12
The a7 III body construction features a lightweight, high-rigidity magnesium alloy for the internal frame as well as the top, front, and rear covers. The grip area has also been reinforced with an integrated magnesium alloy front cover. The number of screws securing the lens mount has been increased to six in order to maximize rigidity and durability even when using heavy telephoto lenses.
Anti-dust system and coating
To keep your photos blemish-free, a special anti-static coating on the surface of the optical filter suppresses the attachment of both dry and moist dust particles when changing lenses. An anti-dust mechanism also vibrates at high speed when you select Cleaning Mode, to remove any particles adhering to the filter.
