When in manual focus mode, the the digital magnifier turns on to help focus - sometimes this helps and sometimes it's just annoying, so it would be nice if we could toggle that on and off (oh well!).
This is sort of a fix for that. When you got something in your sights and you're in manual focus mode, half-press the shutter. This allows you to focus without having to endure the zoomed in mode. Naturally, this isn't as great as actually getting the option to turn it off completely, but it's at least something.
