Let’s have a look at some images made with the Sigma SD1. Here’s a detail of a simple single-light portrait cropped in to just my eyes. This shot was made with the Sigma 85mm F1.4 on the SD1 at 1/160 @ F/16 @ ISO 100, and processed in Sigma Photo Pro as a Double-Sized 16-bit Tiff, which was then cropped in to just my eyes. (File dimensions before web optimization: 6272 x 4181 px, here it is optimized for the web at 1500 x 760 px) After the jump we’ll look at a slice of this shot at the “actual pixels” level.
