Sony a7S Overview
The Sony a7S was announced on April 6th, 2014 and offers 8-bit 4:2:2 4K video over HDMI at up to 30p, without the need for line skipping or pixel binning.
It can also record 1080p video (at up to 60p) internally and offers the XAVC S system, with bitrates of up to 50Mbps.
The ‘S’ in the camera’s name denotes ‘sensitivity’ and for movies it offers an ISO range of 100 to 409600. For stills it offers ISO 100 – 102400 extendible to ISO 50 – 409600.
The a7S also includes time code with userbit (user-applied metadata to help at the editing stage) and a range of movie-centric S-Log2 gamma, along with several Picture Profiles.
DPReview awarded this camera their Gold Award and concluded their in-depth review with the following:
Its 1080p footage is the cleanest, most detailed we’ve yet seen, with virtually no moiré and often jaw-dropping low-light performance. Some of the low light advantage is undercut if you need to stop-down to achieve sufficient depth-of-field but, unlike smaller sensor systems, you have the choice over whether to do this or whether to embrace the shallow-depth-of-field and low light capabilities.DPReview
If you are looking for a low cost full-frame 4k video shooter that excels in low light, then the a7S is still a fantastic piece of kit.
If you have a little more money in your pocket then you might want to take a look at my Sony a7S II vs a7S III comparison.
