I take pics in night clubs were low light and no composition make life hard currently i am using a Canon S50 with mixed resaults. The two cameras that i have narrowed down to is the canon G6 with a fast lens and the Canon Pro 1 with a beter quality lens but no focus assit lamp. so the camera i get needs to focus in low light and be quick to record a shot. Cost is not an issue size needs to be smallish. I am also looking at getting a Canon D20 for my outdoor product shots. Any help would be welcomed
