4K video output via HMDI ; Lots of control over video ; Maximum sensitivity setting of ISO 409,600

Low pixel count for stills ; 4K recording only via an external recorder ; Lens range currently limited

It's a great camera but its comparatively low pixel count and high price mean it's unlikely to have wide appeal amongst enthusiast photographers. However, it will find favour with those who need to be able to shoot in near-dark conditions or want lots...

Great full-frame image quality, sturdy build and small scale design, great electronic viewfinder quality, tilt-angle LCD with large view, two batteries included

Poor battery life, no wall charger means slow charge, full-frame lens range is lacking, AF-C not comparable to £2k DSLR, 4K capture off-camera only, much pricier than standard A7

Just like the original A7, the A7S is mini marvel with a massive sensor. It's the new 12-megapixel chip that's the main point of interest as image quality is the cleanest out of the current trio of A7 cameras available. That will benefit those who...

Shoots 4K video ; Excellent in low light ; Huge, bright OLED viewfinder

4K recording requires external device ; 12.2MP sensor seems limiting for stills ; Very expensive

A filmmaker’s dream – but still photographers may be better off looking lower down Sony’s range

Sony’s strategy of using larger pixels on a full-frame Exmor CMOS sensor (12.2MP) pays dividends in a very high dynamic range (15.3 stops), excellent low-light capability (Fast Intelligent AF to -4EV and low noise) and extremely high sensitivity...

12 megapixel files are smaller ; Impressive ISO range available for stills and video ; Very impressive noise performance up to ISO25600 / ISO51200 ; Full-frame sensor mirrorless camera ; Focus peaking / Zebra display ; 5fps continuous shooting (speed...

4K only available when recording to an external device ; 4K external recording device isn't available yet ; High price if you want to record 4K video ; Limited lens range in FE mount (plenty of adapters available) ; Flash not included / provided -...

The Sony Alpha A7S bucks the trend for more megapixels, by offering a 12 megapixel full-frame sensor, this gives it impressive light capturing abilities, with low noise right up to ISO25600 and above. The smaller file size should also let you shoot...

Impressive image quality Superb, detailed, essentially moiré-free 1080p footage Outstanding 4K (UHD) video when used with external recorder Useful, high resolution electronic viewfinder Completely silent shooting available Microphone and headphone...

Limited to contrast-detect AF, while a7/II siblings have on-sensor phase-detect AF Lower dynamic range and resolution than immediate competitors Sony's Raw compression scheme can lead to posterization at high contrast edges Small battery can be...

The Sony a7S is an interesting departure for a camera company: a model where possibly more of the emphasis during the design process has been placed on video capture, rather than stills. This is made easier to see by the existence of its sibling...

Amazing high ISO capability. Full-frame image sensor. 5fps burst shooting. Sharp, tilting rear LCD. Excellent OLED EVF. Great control layout. Compact, dust and moisture-resistant body. Vertical shooting grip available.

4K recording requires external recorder. No PC sync socket. No built-in flash. Limited native lens selection. Overactive EVF eye sensor.

The EVF is an OLED panel with a 2,359k-dot resolution, similar to the one found in the APS-C Alpha NEX-7. It's one of the best you'll find in a digital camera, although we give slight preference to the LCD EVF in the Olympus OM-D E-M1. The LCD tends to...
