One thing which isn't terribly well covered on the various reviews I read about the RX1, is how well it does or does not focus in lower light situations. Vaguely, most of the reviews simply say that it's not "great" but never seem to elaborate. So, those of you who have the experience, how would you characterize such abilities? One of my primary reasons for considering the RX1/RX1R is to have a small, high-quality, but especially well-performing low-light camera. I'm not talking about extremes, such as star / moonlight situations. But realistic situations, like shooting in average to poorly lit indoor situations. Family gatherings at home. Dining at restaurants. That sort of thing. Thanks.
