AutofocusHybrid phase/contrast detection, 493 single-point FX still positions, 3D tracking and subject detection including people, animals, birds and vehicles/aircraft. Maker sensitivity −7 EV or −9 EV with Starlight View, measured in AF-S at ISO 100, 20°C and f/1.2.Fast Hybrid AF; up to 693 phase-detection points for stills or movies; EV -4 to 20 at ISO 100 with an f/2 lens; current maker subjects include automatic selection, humans, animals, birds, insects, cars, trains and aircraft
ShutterElectronic shutter only, with selectable sound and sensor shield; 1/32000 to 30 seconds, Bulb/Time and manual-mode extension to 900 seconds. Flash sync 1/200 or 1/250 second with reduced guide number at the higher speeds; compatible Auto FP up to 1/8000.Electronic first-curtain mechanical shutter up to 1/4000 second; silent electronic shutter up to 1/8000 second; 30-second exposures and Bulb; flash sync 1/160 second full-frame or 1/200 second APS-C with Sony flash
Burst detailContinuous high-speed shooting up to 20 fps for full-resolution RAW. High-speed capture C15/C30 uses large FX or DX JPEGs, C60 requires large DX JPEGs and C120 requires small FX JPEGs (4128 × 2752). High-speed burst length varies by frame rate according to the current manual; these restricted JPEG modes are separate from the main continuous RAW figure. Pre-release capture available. Current manual restrictions take precedence over UK marketing prose and TechRadar's erroneous full-resolution 60 fps claim.Up to 8 fps Hi+; maker buffer approximately 36 compressed RAW, 16 lossless-compressed RAW or 14 uncompressed RAW images; up to 320 Fine JPEGs. Amateur Photographer found 8 fps requires compressed RAW without live view, and 6 fps with live view or lossless-compressed RAW.
