I just bought a gf2 and the highest iso I can go is 400 for usable pics of decent size. Is this realistic? I was looking at some pictures I took with a nikon D5000 in auto mode, and I have out of camera jpegs at iso 1250 that i could print. GF2 iso 400 = nikon D5000 iso 1250 Please tell me I am doing something wrong. And for those not familiar a Nikon D5000 is an older entry level dslr with same megapixels as the gf2.
