Lens detailAF coupling supports compatible screw-drive lenses. Supported non-CPU AI lenses permit aperture-priority and manual exposure; entered lens data enables colour matrix metering. IX and F3AF lenses unsupportedInterchangeable Sony A-mount; compatible Sony, Minolta and Konica Minolta AF lenses; kit optics are separate from body specifications
AutofocusMulti-CAM 3500DX phase detection; 51 points including 15 cross-type; single-point, auto-area and dynamic 9/21/51-point modes with 3D tracking; AF fine-tuningTTL phase detection with 11 points, centre dual-cross sensor and additional F2.8 precision sensor; single-shot, automatic and continuous AF, direct manual focus and manual focus; selectable Eye-Start AF; EV 0–18 detection at ISO 100; dedicated AF-assist lamp
Shutter1/8000 to 30 seconds and Bulb; standard flash sync 1/250 second, with 1/320 available at reduced flash range; shutter tested to 150000 cyclesElectronically controlled vertical-traverse focal-plane shutter; 30 seconds to 1/8000 second plus Bulb; flash sync 1/250 second with stabilisation off or 1/200 second with it on; Sony rates durability at approximately 100,000 cycles
Burst detailApproximately 6 fps with the body's EN-EL3e. Up to 8 fps using MB-D10 with EN-EL4/EN-EL4a or eight AA cells, or EH-5/EH-5a AC power; an EN-EL3e in the grip alone does not provide 8 fps. 14-bit RAW limits speed to approximately 2.5 fpsUp to 5 fps Hi or 3 fps Lo; Sony’s Japanese table claims 16 Extra Fine JPEGs, 18 RAW, 25 cRAW or 12 RAW/cRAW+JPEG frames; Standard/Fine JPEGs can continue to card capacity. Shooting conditions and card speed affect results; PhotographyBlog lists lower RAW/cRAW buffer counts.
