in my experience, there is a huge jump in high-iso performance of PS vs DSLR cameras. now im not familiar with this fuji model in specific, but if it has iso400 performance equivalent to canon's 200.. its just a 1-step advantage. personally, for any exposure faster than 1/30 and it doesnt make a difference, and anything slower than that makes no difference either because theyll both be blurry hand-held! where they converge in low-light situation is, in a snap of the finger, i can adjust iso / flash mode / shot vs timer / white balance / etc on the canon to get a proper shot. that, to me, is better than a 1-step sensitivity advantage.
