I consider ISO 1600 not-usable on my otherwise great Panasonic GF1. I've heard the Olympus E-P1 is better in this regard, does anybody know, or know of a direct comparison? I'm particularly concerned with loss of detail and "mushiness". (By the way, does anybody know a way of influencing noise reduction in the GF1, apart from film mode? (I don't even know what film mode does.)) Update: found this so far: http://www.imaging-resource.com/PRODS/DMCGF1/DMCGF1A7.HTM http://www.imaging-resource.com/PRODS/EP1/EP1A7.HTM It seems that the EP-1 has more detail at 1600 ISO, but then it has more detail at 200 ISO also, so maybe it's the lens?
