Sony A7S is a 4K video recording full frame mirrorless camera designed for both stills and video. After the new A7s officially announced probably everbody wants to see the results of its low-light capability.
At first DxOMark posted their sensor review and test results for the Sony A7s and it has become the low-light king in their database. The mirrorless camera easily beats the Nikon Df which is the second best camera with a $500 higher price.
Now Dpreview posted their high iso comparison charts and Sony A7S vs. A7R vs. Canon EOS 5D III shootout. According to their conclusions at ISO 204,800 and beyond the Sony A7s has up to a 2 EV advantage and at moderately high ISO performance the A7s has up to a 1 EV advantage in shadows. Finally there is no difference between the cameras at low ISO.
Sony A7S vs. A7R vs. Canon EOS 5D III High ISO Comparison
The Sony A7S features a new 12.2-megapixel with a 35mm full-frame sensor, 4K movie recording, ISO 50 to 102,400 (extendable to ISO 409,600) and an improved auto focus system that remains operational down to light levels as low as -4EV.
From Dpreview conclusion :
The Sony A7S enables the use of incredibly high ISOs, including some unavailable to most cameras. When shooting at incredibly low light levels, the A7S will most likely give you significantly better results than any camera that does not natively shoot at these ISOs. There are also some advantages to be had over the higher native ISOs of the cameras we tested: we see the A7S overtake the A7R in normalized shadow noise performance at ISOs above 6400 in our tests. At more moderately high ISOs (6400 and below) as well as in brighter regions of images – where image quality is determined primarily by how much total light is captured – the normalized ISO performance of the A7S will be similar to that of full-frame cameras of its generation.
