Is any camera really up to this task?
I'm not sure I understand your question. The wedding was a very relaxed event and I just wanted to make good enough pictures, which I did. We were not even in a church, but the light was very low both during the marriage and the party afterwards.
I know I have the skill too shoot stuff like this with proper gear, and the RX1 had many advantages such as being unobtrusive and dead quiet. If AF would have been faster, I'd recommend it as a second camera straight away. Edit: Of course it could be the ultimate second camera, but not as a backup! Just for snaps and the unobtrusivness, combined with fantastic IQ under circumstances when no one would have expected it.
Anyway, I got the proper images that I really wanted and my brother and his wife are very happy with the results.
