DxOMark has just reviewed the Zeiss Otus 1.4/55, a $ 4000 standard prime for full frame SLRs, and as part of our ongoing collaboration we’ve added the test data to our lens widget. We’ve also added test data for the Nikon mount version of Sigma’s exception 18-35mm F1.8 DC HSM. Click through for more details and analysis, including a comparison between the Zeiss 55mm and the Nikon 58mm f/1.4G, and a link to DxOMark’s own review.
