Great lens for the price. Nearly the full-frame equivalent of the 35mm f/2 in Sony's APSC range. Focusing is smooth and accurate. Not as quiet as my native Sony lenses, but not bad either. Sharp in the center, slight vignetting wide open. Excellent build quality, metal hood. You can't win at this price. Will be updated if problems arise. EDIT: Having an aperture ring is nice, but not being able to lock it is very annoying. It's not uncommon for me to accidentally rotate my ring from "A" mode to f/16 mode, which is a bit annoying.
