With the Sony Alpha A7 III you have the capability to capture images in the peaks of decisive moments, with the enhanced newly developed back-illuminated full-frame CMOS sensor and other advanced imaging innovations. With high-speed response, with the ease of operation, and reliable durability that are ready for various shooting needs.
FIRMWARE UPDATE 3.0
Newly developed sensor evolved image processor
The new 24.2-megapixel Exmor R™ CMOS sensor, now features a back-illuminated structure, which is combined with the latest BIONZ X™ image processing engine, as well as front-end LSI. With this combination the Sony Alpha A7 III is able to achieve data processing ability that's 1.8 times higher, and a data readout speed that is twice as fast.
Light collection efficiency is enhanced with the 35-mm full-frame CMOS image sensor with back-illuminated structure. As well as expands circuitry scale, with the help of a copper wiring layer for quicker data transfer, which can output data at a high speed while still minimizing noise for fine details in every image.
With an approximate 15-stops of dynamic range at low-sensitivity settings is achieved, this is because of the new revamped CMOS sensor and image processor. Which provides for smooth gradation from highlight to shadow. Giving you the freedom of creative imaging.
The color reproduction performance is incredibly enhanced, giving you image subjects a more natural color that is true to the colors in real life. Being in skin tones, portraits, blue skies of landscapes, and vivid hues in still life images. Giving you a very realistic image result.
With an 1.5-stop improvement in image quality
The standard ISO range is extended to ISO 100-51200 (expandable to ISO 50-204800 for stills), while the technologies of Detail Reproduction and Area-specific Noise Reduction maintain image details and decrease noise. With a highly effective performance in mid-to-high sensitivity ranges, you are able to shoot at high ISO with no concerns about image deterioration or noise.
Steadier shots with 5-axis stabilization
Latest high-precision stabilization uses the stabilization unit, gyro sensors, and algorithms to produce a 5.0-step shutter speed. This is an advantage in a system that compensates five types of camera shake, and has a wide range of lenses that deliver excellent performance.
4D FOCUS—AF performance evolves
The Sony Alpha A7 III features a 693 phase-detection AF points which covers an approximate 93% of the image area, plus there is 425 densely positioned contrast-detection AF points in order to improve overall focus.
With combining focal-plane phase-detection AF this produces excellent speed, tracking, and high-precision contrast-detection AF. Sony provides a sophisticated Hybrid AF which captures fast-moving subjects with razor-sharp images, this provides up to two times as fast AF performance.
The advanced AF algorithms of the A7 III contribute to a high AF precision with light levels as low as EV-3, giving you a more reliable autofocus in dark scenes.
Now the Eye AF can be used in AF-C mode, for a faster, effective eye detection, and tracking performance with still photography. With the easy maintenance of the optimum focus on moving subjects, you can transform your portraiture. This is applicable even when the subjects face is partially hidden, backlit, or is looking down.
The Sony a7 III has Touch Focus function, complete with a touch pad function that allows you to intuitively fingertip-drag the focus frame while using the viewfinder.
More versatile AF settings all around
The AF tracking sensitivity for stills is adjustable in five steps. The AF areas/points are changeable when changing between horizontal and vertical orientation. The focus point settings can be assigned to custom buttons.
The Sony a7 III has the capability to shoot in a continuous burst at up to 10fps, and AF/AE tracking up to 8fps in burst shooting with live-view mode shooting. This camera supports silent shooting at up to 10fps with AF/AE tracking at maximum resolution.
With continuous shooting of up to 10fps—or 8fps capture an instant action shot for live-view shooting—with AF/AE tracking. In one continuous burst approximately 177 JPEG (standard) images, 89 compressed RAW images, or 40 uncompressed RAW images can be captured.
The A7 III allows for silent shooting up to 10fps with AF/AE tracking. This being critical for scenes when silence means not missing your chance at an ideal shot.
High-Quality 4K HDR for Video Professionals
New video capabilities of the A7 III include the ability to record stunning 4K movies 2.4-times the higher oversampling, the A7 III also features a new Hybrid Log-Gamma (HLG) picture profile, which supports instant HDR workflow.
Condensing approximately 2.4 times the data for 4K movies, for full-pixel readout without binning in 35-mm the full-frame mode. Overall minimizing moiré and jaggies. The Super 35-mm of full-frame mode can be selected as needed. The 4K video recording employs XAVC S format at bitrates high as 100 Mbps.
The fast Hybrid AF with a focal-plane phase-detection AF, and contrast-detection AF is able to smoothly track and lock onto subjects. This wide AF area is available for still images as well as movies. With a reduced low-end AF drive speed this allows for more pronounced slow focus effects. Giving you the freedom to match focus response to specific scenes.
The improvement in S-Log3 helps to improve gradation from mid-tones to shadows while widening the dynamic range up to 14 stops. You can also . choose to select a frame rate from 1 to 120/100 fps for up to 60 times quicker motion and 5 times slower motion.
The shutter speed is times to minimize the possible color inconsistency and exposure in images when artificial lighter flicker is detected. With images shot at high shutter speeds, and continuous shots.
Dual media slots, UHS-II support
With UHS-II compatibility and two media slots, The Sony a7 III can relay record, separate RAW or JPEG data and movie/stills, as well as copy data between cards.
Long-lasting Z battery
The NP-FZ100 Rechargeable Battery has a high-capacity of approximately 2.2 times the NP-FW50 W-series. Giving the a7 III the longest rated battery life of any Mirrorless camera at 710 shots per charge.
