Got my copy of this lens. Shot a few indoors wide open, manual focus. Images sharp, sharp, sharp. As sharp as anything I've ever seen, even in the corners. Went outside and found everything was soft, looked crappy edge-to-edge. Did a search here and found an article about how these lenses sometimes don't focus to infinity. A few more tests confirmed I was way short. A drag, but fixable, thanks to Quatchi's instructions on the forum. [DIY] Fixing the Rokino/Samyang/Walimex 7.5 MFT Fisheye Focus Issue Not thrilled but sure better than mailing lenses back and forth until I got a perfect copy. Hope I get decent weather Saturday to do this right. Nice to have such a great resource in the knowledge bank of our members. P.
