This doesn't entirely belong in this thread, but it sort of does. Just wanted to throw up a quick and dirty comparison the first DA 15mm shot I posted out my window the other night (a few posts up) with this one, taken with the Ricoh GR with the 21mm adapter that just arrived this afternoon. It's out the same window, processed as closely as I could, working quickly. Not an entirely fair comparison, the Pentax had the benefit of a city-lit clouds passing by, while tonight it's clear and black up there. Nevertheless... I'm awfully impressed with the Ricoh in this case.
