I like to use it on my Olympus E-PM1! Unfortunately it looks like the Micro 4/3 variant is currently unavailable, hopefully it will come back. The lens sticks out about 40mm from the mount and is quite heavy, so I prefer to use it with two hands, even with the depth-of-field aperture closed. My copy weighs 239 grams without filters and caps. For manual focus, I really like that the dial only covers about 60 degrees of rotation - I used to have a Meike 35mm f1.7 and this focus wheel covered almost 180 degrees. Manual focus seemed more accurate on this lens, but too slow for me. There are a few downsides to this lens though: I don't like that the focus can go beyond infinity, and it's a bit odd that the focus wheel is on the back and the aperture wheel is on the front. I am 100% satisfied with the exchange. I don't have a good way of judging sharpness, but I'm quite happy using it wide open and up close to isolate objects in the center of the frame, and at f8 for deeper landscape shots, I'm quite happy with that Edge-to-edge results. I also did a quick, non-scientific exposure test in aperture mode versus an f1.7 lens, and the f1.2 setting seems to gather more light than advertised. A final note on small branded lenses: I enjoy reading reviews from Alik Griffen which usually point out some technical imperfections of these lenses but emphasize that they don't really detract from the fun and versatility of these lenses. It also tends to check larger sensors than the Micro 4/3. So if you have a Micro 4/3 that doesn't even cover the entire lens range, these technical flaws probably matter even less.
