Is any of this not true? (1) Peaking does not work in AF. (2) MF assist does not work while recording movies. (3) There is no way to set MF assist to work with a custom key but not with the lens ring; it's all or nothing. (4) MF assist (i.e. zooming in) does not work in AF. (5) It is not possible to decouple AF from the shutter button. Don't get me wrong, MF assist and peaking are nice features, but these five limitations don't need to be that way, do they?
