Hi all, just sold my EM1 and was thinking of gooing full frame with a Nikon D600, then i started looking at the fuji thread! One thing that concerns me is i mainly take indoor portraits of my kids and want great high iso performace. Is it correct that the xt1 raw iso tops out at 6400? Also i read bits and bobs that fuji fudge their iso ratings? I was thinking of an XT1.
