I have a CPC Phase 2 28mm f2.8 macro. I paid $20 and I looove the FL and colors on m4/3s but I want something with better corners and better contrast wide open I guess I'm leaning towards the Pentax M 28/2.8 (version 2 is better than 1, apparently). I prefer the look/feel of Pentax but I won't rule out the Konica Hexanons if they have an advantage. A couple people have said the Pentax 28/3.5 is sharper than the 2.8 but I haven't seen any comparisons. I see some Sigmas (both in 24 and 28mm) that look good in samples, have macro, and are cheap to boot, but can they compete with the lenses mentioned above? I'm confused by them because they come in various mounts. I'm open to suggestions. The better the lens the more I'm willing to spend but I will not spend $900 for the Pentax 31/1.8! I've been looking through these 24mm and these 28mm samples. I think I actually prefer 28mm because 24 is getting close to the Pany 20/1.7 which beats them all (I guess the m4/3s Sigma 30/2.8 probably beats most of these 28mm too but there's just something satisfying about manual focus!). UPDATE: Looking through the threads Kiron/Vivitar is actually impressive. I wonder why some say "close focus" and some don't. Also, the f2 is the obvious choice over the f2.8, but if the 50mm's are any example, the 2.8 is sharper (with most 50s I've seen you're better off getting the 1.8 than the 1.4).
