Since Sigma 35mm f1.4 appeared it has being a frequent subject on forums and within photo community in general. Most of the early users claim it works beyond expectations and counts into one of the best lenses produced by this company. How good it really is compared to "golden reference" Zeiss 35mm f1.4 I decided to find out using good old Imatest testing package. Another two runner ups are included: cheap Nikkor 35mm f1.8G and Micro-Nikkor 40mm f2.8G. First chart published shows center resolution only.
