Recognition covers people, animals, birds, insects, cars, trains and aircraft; Auto subject recognition supported. AF-S sensitivity is EV −6 to 20 with F1.2 at ISO 100, or EV −11 to 20 in the specified Bright Monitoring mode.Current Sony specification lists 693 full-frame phase-detection points and 425 contrast-detection points; contrast points increased from 25 through firmware. Phase coverage approximately 93%; sensitivity EV −3 to 20 with an F2 lens at ISO 100. Current features include Real-time Tracking and Eye AF; launch reviews describe earlier firmware.
