I know it looks funny mounted on a G1 (let alone a GF1!), but last night I (finally) had an opportunity to use the one I bought a while ago for the first time. This morning, looking at the images I captured, I'm blown away by its 1) its IQ and 2) its resolution ... as I said, Wow! I don't know if I dare to ask (as I've also just purchased a 35-100 f/2 ... ka-ching!), but does the 7-14mm also perform this well?
