I did it again and it worked. The adjustement stayed in canon menu even after disabling dottune menu. That was with 18-135 lense. Works like charm. Sadly, with 35 f2.0 canon IS lense the procedure doesn't end. LCD screen goes black and nothing happens. After few minutes camera goes standby. Both are registered. With prime lens i'v chcecked box in menu only to adjust "W".
