The A7S III features a 12.1MP resolution spread across a brand-new full-frame sensor. Sony’s decision to keep the resolution low is single-minded.

Its task is simple – to be the best 4K video camera it can be, excelling when it comes to high-ISO, low-light capture. You can not only record video at up to 120 frames per second but record at up to 60FPS in 10-bit 4:2:2 color for over an hour. Additionally, two codecs have also been developed: XAVC HS, which uses HEVC/H.265 encoding to retain more detail at smaller bitrates, and XAVC S-I, which is an intraframe codec for consistent performance and quality at bitrates up to 600 Mb/s. XAVC HS format uses MPEG-H HEVC/H.265 codec for more efficiency.
