First Look: Sony a7S III

Building upon the success of its predecessor, the new Sony Alpha a7S III has been updated with several standout features focused on video. With an updated BIONZ XR processor and new 12.1-megapixel BSI Exmor R sensor, the a7S III packs powerful internal recording options, including full-frame 4K 120p and S-Log2 and S-Log3 support, all via the new XAVC HS format, an HEVC / H.265 based 10-bit 4:2:2, intra-frame (All-I) codec. External output options include 16-bit RAW via the full-size HDMI (Type A) port to a compatible recorder, up to 4264x2408 (16:9) at 60p.

The new processor allows for faster sensor read out, significantly reducing rolling shutter distortions, while a new heat sink design allows for indefinite record times. The Hybrid AF system combines phase detect and contrast detection auto focus, resulting in smooth focus transitions that can be further customized with a new AF Transition Speed option, allowing for truly cinematic focus pulls.

A few weeks ago, I was fortunate enough to spend an afternoon with Gene Szucs, Sony Imaging Specialist Territory Manager, who brought along the a7S III so I could go hands-on with it. We explored the new capabilities and features while shooting some test footage. Watch our video above as we discuss these updates and more!
