24.2MP Exmor RS BSI Stacked CMOS Sensor and BIONZ X Image Processor
The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with a wide dynamic range with smooth tonal rendering. Benefitting the fast recording capabilities is an equally quick AF/AE metering system that functions at 60 times per second to continuously evaluate the scene in order to lock onto and track moving subjects. Automatic anti-flicker shooting also recognizes and times the shutter action to minimize the flicker effect for more consistent results on still images. Additionally, due to the use of an electronic shutter, totally blackout-free monitoring is possible with the electronic viewfinder for more accurate compositions of moving subjects.
Fast Hybrid AF System
The apt focus system also lends itself to a variety of focusing functions for refined accuracy, including Lock-on AF, which maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject, and Expand Flexible Spot, which employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus. The focus frame color is selectable, between white and red, and AF tracking is possible with apertures narrower than f/16 with select lenses when working in Focus Priority mode. Additionally, Eye AF can be used to base focus on recognized human subjects’ eyes for portraits and is available in both AF-S and AF-C modes, for both stills and video. Eye AF can be used when photographing animal subjects, too, with any focusing mode when shooting stills.
