After a long five years since the A7S II, Sony finally launched a proper successor with the A7S III. While it still uses a 12.1-megapixel sensor (but this time a BSI one), the A7S III can shoot 4K video at up to 120FPS or up to 240FPS in Full HD. For recording formats, you can choose between H.264, H.265 HEVC, or 10-bit 4:2:2 HLG HDR for internal recording, or 16-bit RAW video using an external recorder.
Together with an all-new BIONZ XR image processor now has a standard ISO range of 80-102,400 (which can be (expandable to 80-409,600 for video and 40-409,600 for stills—an incredible range especially video), along with a new Fast Hybrid AF that combines phase-detection and contrast-detection AF with Real-time Tracking and Real-time Eye AF for both stills and video.
Speaking of autofocus, the A7S III has 759 phase-detection AF points that covers 92% of the image sensor, and still works even at EV -6. For burst speeds, the A7S III can shoot over 1000 uncompressed RAW images at up to 10FPS (8FPS in live view mode).
While it can shoot 8K video like the EOS R5, the A7S III’s claim to fame is that it can shoot 10-bit 4:2:2 4K60 video for over an hour or until it runs out of battery power. This is made possible by a newly-developed heat-dissipating structure that does not require any fans or vents in order to maintain the A7S III’s dust and moisture resistance.
Other new features on the A7S III include dual slots for UHS-II SD cards or CF Express Type A, a 9.44 million-dot OLED viewfinder, 5-axis in-body image stabilization, a 3-inch fully-articulating touchscreen display with a 1.44 million-dot resolution, a revised menu interface, and a new battery that claims to offer up to 60% longer record times than the A7S II.
The A7S III will be available in the US in September and in the Philippines this October. It will retail in the US for $3498(~Php 172k).
