Dedicated image plane phase detection AF pixels are used to calculate lens position and subject distance. Up to 192 AF points can be used. All calculations are instantaneously carried out by the stacked CMOS image sensor's internal image processing circuits:

HDR function works by setting two different exposures and applying the appropriate signal processing. Through improved pixel placement and signal processing, this new HDR imaging function is now compatible with both video recording and, by popular demand, still image capture, the latter a feature that was not available previously. (video HDR was first announced in 2012. When using the HDR movie function, the effective pixel count is reduced to 1/4 of its original number.) HDR function is also compatible with 4K video recording.
