Hi, just a R5 feature request to be able to allocate a button to preview ambient exposure when a flash is attached to the hotshoe. My current workaround/hack is to enable Expo. simulation and assign DOF preview button to Cropping/aspect ratio, I can then press DOF twice to simulate ambient exposure then 1/2 press shutter button to return to the normal viewfinder when flash is attached. Would be better to just be able to select it once and use the shutter 1/2 press to go back. Unless I am missing something? T
