Hello I use an 50mm 1.4 M lens. I cannot say a bad thing about it. But it is manual focus and manual apeture. My approcah to the problem is that I buy Manual lenses becase I can. I could not but AF lenses. I am not to found of the Auto apeture cameras (P series, Programme, super programme, etc.) so I do not need A lenses.
If I will ever have a crapload of money to spend on autofocus equipment I will buy az MZ-3 or MZ-S, the 3 limited lenses, a good AF zoom and an FA-50 1.4 but right now I do not have a couple thousand to blow. So, your ZX-M (MZ-M) is compatible with auto apeture lenses. (I think) A lenses are about the same price as M lenses, so get A lenses. Though I might be starting a debate on quality, but optically they are comaparable, as far as build, the Ms are better but if we compare A to F or FA you are getting the same quality...correct me if I am wrong) If the f2 is enough fo you, and you do not want to use auto apeture keep the manual lens, don't upgrade. (keep it anyway, it is not worth much, in fact people say that from the buyers point of view that is the best price/quality lens you can get) If you need a faster lens, consider a lenses, then decide if you want faster or smaller. If you want faster get an A 1.4 (keh.com has a few, they pop up on e-bay too) If you want smaller/lighter get an A 1.7. (that is usually all over e-bay) If you are really serious about autofocus, I have heard only god things about the 43mm Limited lens. But it is only an f1.9, if you need more speed, 50 f1.4 is the way to go (if I could, I'd get both and use the one that better fits the light conditions :)) Oh yeah, as far as f1.2 goes. I have heard bad things about those. They say that you really need a good justification to get one because the only benefit you will get is in low light situation. Any other time and place they are optically infrior then their f1.4, f1.7 and f2 brothers. (this might start a fight too :)) L - This message is from the Pentax-Discuss Mail List.
