I was just watching these as in thinking of adding a fast wide lens. Thought these were simple and very well done. My favorite part is near the end where he puts a few similar lenses side by side. I was all set to go Olympus, but I have to admit that the Pany 15 and 25 look very nice. Of the three - Oly, Voigtlander, Pany, I though Pany were great. I was surprised that the Olies look a little muddy, for lack of a better word, in comparison. Do you think that may be due to the video only comparison and not indicative of stills? Of course no one else may agree with my opinion. I'll have to watch again, but I liked this format of test. I wish all provided this kind of controlled, identical side-by-side.
