While I dont have it, I too periodically think about getting this lens. I have 4 other m-hexanons and I'm overall a big Konica fan. However, in case of this lens I cant seem to make up my mind. I know its sharp. I know it's modern. Yet something is missing. I think my Hex 50/2 has more character, at least to me. For faster lens, I have Canon ltm 50/1.2 - has a lot more flaws, but character is there. I have CV 35/1.2 - great lens, sharp, great signature - but it's better to me as its easier to focus wide open as its 35mm vs 50mm, it has closer min focus - .7m vs .9m (correct me if I'm wrong here), and is much cheaper.
If I could find Hex 50/1.2 for the price of CV 35/1.2, I'd probably get it, but as it is I'm still unsure about it.
Great lens, though. Maybe one day I'll break down and get one.
