The X-Pro2 has a decided bluish cast to the EVF compared to the LCD... bothers me... especially because I mostly use the EVF and it does not match the LCD or what I see with my eyes. On the X-Pro I keep EVF at 0 and LCD also 0... both manual
With the X-T2, the EVF is a bit brighter than the LCD. With the X-T2 it seems EVF on manual is too inaccurate and so far I am keeping EVF brightness on Auto.
With custom WB carefully set and then looking through the EVF and then at the scene itself, the X-T2 EVF seems satisfyingly color accurate to me. The LCD does seem slightly warmer but I need to do some more tests specifically testing them under different lighting.
