The Olympus 12mm 2.0 is well and good, and yes, it is the best lens at that focal distance, but IMHO, for the $800 price tag I think I might be willing to make do with the 14mm 2.5, or even the 14-42mm kit lens (and make do with the 20mm 1.7 in low-light). The 7-14mm is also well and good. It's very sharp and fills its niche well. However, for me, once I'm wide, I'm wide. I don't need zoom. I'm totally fine cropping down to 8 MP, for example. Plus f/4 is slow vs the 12mm. Finally, the lens is very large and $900. Wouldn't it be nice they (preferably Oly) were to make, say, an 8mm f/2.2 prime in a smaller form factor? For that, if sharp, I'd drop the $800!
