that's a wonderful shot richard. i have to admit to still being wary of high iso - and that's because i feel that the one disadvantage of my omd em5 is that it can't cope with high iso in the way that a dslr can. i wonder what you and other experts think? (having said that, i do often go up to 1000 these days, but 6400 would frankly give me the conniptions)
