Last time i wont even bother shooting indoor cultureal performance with a slow kit lens with f3.5 and above cause i will not have enough shutter speed to get a sharp picture. The only solution is to use flash or use high iso. Using flash will spoil the ambience and thus high iso is the only way to go. Luckily the iso1600 on EP1 is very usable compera to my Olympus E3 but what da ya expect!! it is 3 years apart in technology!
