I was just checking prices for the SX10, and found one here for $295.
They also have an adapter listed. I was waiting for Lensmate to make one. This one only supports 58mm filters though. Will the SX10 be able to use 52mm filters? I've got lots of 52mm filters and lenses for my S2 52mm adapter...it would be a real shame if I couldn't use those on the SX10 as well. That might end up being a deal breaker for me.
