I\'m not writing off the Voigtlander 21mm Ultron f1.8 for use on the a7/a7r. Here\'s a shot I took with the lens on the a7r at 1.8 and at quite close focus. Obviously it becomes impossible to judge edge sharpness, but as you can see there is very little color shift even when not stopped down. And the center of the frame is sharp enough wide open to lift the fingerprints of the man\'s hands at ISO 1000 (keep in mind the subject\'s hand was moving). Worst case scenario will be wide open at infinity, and unfortunately given the inside nature of the Vancouver event I was unable to test it. In any case, I\'m cautiously optimistic about this telecentric UW lens.
