24.2MP Full-Frame CMOS Sensor
A new version of the 24.2-megapixel Exmor R™ CMOS sensor, now featuring a back-illuminated structure, is combined with the latest BIONZ X™ image processing engine and front-end LSI, and this combination achieves a data readout speed that is two times faster and data processing capability that is 1.8 times higher.
Reducing noise in high-resolution images
Standard ISO range is extended to ISO 100-51200 (expandable to ISO 50-204800 for stills), while Detail Reproduction and Area-specific Noise Reduction technologies maintain image details and cut noise. With highly effective performance in mid-to-high sensitivity ranges, you can shoot at high ISO with no concerns about noise or image deterioration.
693. Remarkable number of phase-detection AF points
This camera features 693 phase-detection AF points covering approx. 93% of image area, plus 425 densely positioned contrast-detection AF points to improve focus.
10 FPS Continuous Shooting
The α7 III can shoot in a continuous burst at up to 10fps with AF/AE tracking and up to 8fps burst shooting when shooting with live-view mode. The camera also supports silent shooting at up to 10fps with AF/AE tracking at maximum resolution.
4K HDR Recording
Full-pixel readout without binning in 35-mm full-frame mode makes it possible to condense approx. 2.4 times the data required for 4K movies (QFHD: 3840 x 2160), minimizing moiré and jaggies. Full-frame or Super 35-mm mode can be selected as needed. Furthermore, 4K recording employs XAVC S format at bitrates as high as 100 Mbps.
