When I focus my Loxia lens, the movement of the focus ring automatically puts the viewfinder into magnification mode. And, a half-press on the shutter release button returns it back into full-screen mode.
It's a great arrangement; but, unfortunately, I had become used to auto-focus lenses that are triggered to acquire focus by (you guessed it) a half-press of the shutter release button.
There are workarounds, but I think it will be better to break the old habit.
