Full pixel readout in the Super 35 mm mode, without the need for pixel binning, makes it possible to condense 5K (15-megapixel) data into high resolution, extraordinarily beautiful 4K movies with minimal moiré and jaggies. Advanced image processing also allows full-frame 4K movie recording with dramatically improved image quality at mid to high sensitivities. Super 35mm or full-frame recording can be selected as required. Fast Hybrid AF performance during movie recording has been refined, providing a wide AF area that is similar to that provided for still images. AF now accurately locks onto moving subjects over a wider area.
