I see no reason to buy Fuji as it has problematic AF (for many lenses), is 1.5x crop, pricey, poor RS (XH2)
CMOS streaking of Panasonic S5 scares me (saw it in CVP review), I doubt S5II will be better
Canon r8 for 1500 is the most atractive. Remember, each FF cameras doing well in 1.5x crop too, so they are 2in1.
