Don't recall ever seing a test of this but is an IQ180 (280) better in this regard or does the lower base ISO make it worse?For me the big question is how will this new chip on the 260 perform at base iso and up to 400. This is where I tend to be in the field. Can they get more room in the shadows past where the 160 will go now, which I feel is on average about 1 3/4's of a stop to 2.l
Seem to remember users saying the files were smoother at base ISO than the 160 but not sure as the ISO climbs.
