Fast-focusing and 4K-shooting, the Alpha a6300 from Sony is a versatile APS-C-format mirrorless digital camera designed for multimedia image-makers. Revolving around a redeveloped 24.2MP Exmor CMOS sensor and BIONZ X image processor, clean image quality is provided with a wide expandable sensitivity range to ISO 51200, along with accelerated readout speeds for internal 4K30 and Full HD 1080p120 video recording with full pixel readout. Stills shooters also benefit from the apt processing speed, which enables continuous shooting at 11 fps for up to 21 raw frames in a burst, as well as 14-bit raw file output. Complementing both stills and video, the sensor and processor combination also avails 4D FOCUS, which combines a wide-coverage 425-point phase-detection system with a 169-area contrast detection system for quick and precise focusing performance.
Internal recording of UHD 4K movies is possible in multiple frame rates up to 30 fps and, based on the Super35mm recording area and effective 20MP (6000 x 3376) resolution, 2.4x oversampling renders greater detail and full pixel readout is possible, that is void of pixel binning, for higher quality imagery with reduced moiré and aliasing. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both resolutions utilize the 100 Mbps XAVC S format contained within an MP4 wrapper with 4:2:0 sampling. The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate set to either 30p or 24p. In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.
