Well, I for one would love to have a improved focus assist (the zoom-in on the LCD) for manual 3rd party lenses via adapter that's friendlier to use.
What I had in mind is an option to use the Fn button, in any mode (dedicated button, let's call it), so that it would only be active as long as the button is pressed. Finger on it, it zooms, other hands adjusts focus, finger off it, check overall photo, shoot.
#1 - Agree about having a simplier interface when using the older manual focus lenses. (Though I do admit that since getting the EP2 with the EVF I rarely use the magnification mode for manual focusing any more.)
#2 - Better AF - especially in low light. It seems that Oly has tweaked it a bit going from the EP1 to the EP2 (less hunting in low light) but it still falls far behind what Panasonic has managed - and we won't even discuss what is on even entry level DSLRs.
probably my limited ability to search for deeply buried menu items, but I want to kill off the ability to move the focussing rectangle by the little black fourway wheel.
I use manual focus quite often, use the magnified EVF for focussing and do the final framing later in software. It is all too easy to press the button moving the magnified area and as a result get the magnified image out on the edge of the picture.
If it does not exist, please introduce an item disabling movement. If it does exist, please make it easier to find. (yes I know one can disable the face recognition bit, that is not the problem in this case).
