Full-frame sensor and hybrid autofocus

The Sony a7 III pairs a 35 mm back-illuminated Exmor R CMOS sensor with a Fast Hybrid AF system. It resolves 24.2 effective megapixels and reads out data roughly twice as fast as earlier designs. Five-axis in-body stabilisation delivers up to 5.0 stops of compensation for pitch and yaw shake with compatible lenses.

Resolution options and ISO latitude

Still images can be recorded at 6000 x 4000 pixels in full-frame L mode, with additional M and S settings plus APS-C crops down to 1968 x 1312. Native ISO spans 100 to 51200 for both stills and movies, expandable to 50 and 204800 for stills or 102400 equivalent for video.

Battery life and viewfinder ergonomics

CIPA ratings show approximately 610 shots using the 0.5-type XGA OLED viewfinder or 710 shots with the 2.95-inch tilting LCD. Movie recording runs about 115 minutes on the viewfinder and 125 minutes on the monitor, with continuous recording up to 200 and 210 minutes respectively.

Questions about this item

Will the 5-axis in-body image stabilization work with my existing Sony E-mount lenses?

Yes, the 5-axis sensor-shift stabilization compensates up to 5.0 stops of pitch and yaw shake and operates with any Sony E-mount lens; the exact compensation depends on the lens specifications.

How can I confirm the 24.2 MP full-frame sensor is performing correctly after first use?

Shoot a test image at the L 3:2 setting (6000 x 4000 pixels) and verify the file dimensions and EXIF data show 24 megapixels and the selected ISO range of 100-51200.

What accessories are included with the body-only package and what must I purchase separately?

The box contains the ILCE7M3/B camera body, NP-FZ100 rechargeable battery, charger, strap, body cap, eyepiece cup and cable protector; you must buy an E-mount lens and memory card separately.
