The first few images were all shot in an extremely dark venue. The primary light sources were two light bulbs; one with a red gel and one with a yellow gel. Tech Specs: ISO 25600, 1/160 sec, at f/4.

The Sony A7S is a particularly unique camera for two reasons: the first is its ability to recored 4k video. The second, its extraordinary ISO range, which, along with the Nikon D4s, is in a league all of its own. We were curious to see just how well the A7S handled itself at some of these higher ISOs, especially in real world scenarios, so we put it to the test, first at a very dark venue.

The images in the gallery to the right were all pulled directly from the camera and shot in the sRGB colorspace. The vast majority of them were shot using a Sony Zeiss Vario-Tessar FE 24-70 f/4 lens ZA OSS lens, although where noted, a Sony Zeiss Vario-Tessar 35mm f/2.8 was used. We tried to stick with low light situations, although we did shoot a couple of daylight images as well.

Skin tones lit by red-colored light present a particular challenge for camera sensors, in terms of recording detail, however the A7s seems to handle itself well in these type of scenarios. Tech Specs: ISO 20000, 1/200 sec, at f/4.

This image is fairly underexposed, yet the lack of noise gives us hope that with some work in Lightroom, this image can still shine. Tech Specs: ISO 20000, 1/1200 sec, at f/4.
