Michael1 Posted June 18, 2014 Share Posted June 18, 2014 DxOMark has the test scores in for the Sony a7S. It's the new low light king with a ISO score of 3702, edging out the Nikon Df's score of 3279, and D4 with 2965. Others, Canon 5D Mk III at 2293, and Nikon D610 at 2925. When compared to the Canon 5D Mk III, the dynamic range was higher at all levels by about one stop, and more above ISO 6400. When compared to the less expensive Nikon D610, the a7S again pulled ahead above ISO 1600, but below 800, the Nikon came out on top, with about one stop advantage at 200 and below. Tonal range were similar for all, until ISO 128,000, where the Sony pulls ahead. S/N ratio is surprisingly close for all, until 512,000, where again the Sony leads (whose going to shoot there anyway). Color Sensitivity between the Sony and Nikon are similar, with both slightly edging out the 5D. The Nikon tops the Sony below 400, and the Sony pulling ahead at 128,000 DxOMark Overall Scores: Sony a7S=87 Canon 5D Mk III=81 Nikon D610=94 Michael Quote Link to comment Share on other sites More sharing options...
liork Posted June 18, 2014 Share Posted June 18, 2014 Where are the 15.3 promised stops? Quote Link to comment Share on other sites More sharing options...
Guest Ebrahim Saadawi Posted June 18, 2014 Share Posted June 18, 2014 This is thin but, Sony announced a new firmware that claims increasing the dynamic range of the A7s to 15.3 stops. I am wondering if the DxO tests were conducted using the old firmware. http://presscentre.sony.eu//content/detail.aspx?ReleaseID=9810&NewsAreaID=2 Quote Link to comment Share on other sites More sharing options...
