ive been reading the instructions to no avail. maybe im missing something. there are a couple things that perhaps someone can help me out here. i want to be able to set this up to perform like my canon 5d2 if possible 1. how do i set up back button focus? preferably on the Fn1 button? i just want the shutter button to lock exposure and fire just like how i have it on my full sized slrs. 2. is there any way to get rid of all those icons in the viewfinder? all i want is the lightmeter, aperture and shutter. 3. another viewfinder question, is there a way to keep it from brightening up in dark areas? i just want a what i see is what i get just like on a standard mirrored camera. and what is that whirrling sound when i turn on the cam? thanks all! what a great camera so far though. im glad to be here and have found this forum also!
