The accuracy of fit has been described here. However, this is a small obstacle to a quick shot because you need for unpacking too long time. My solution: was at a distance of 1 cm from the left margin and 0.8 cm from the top 2 cm wide and 1 cm high "Peephole" incorporated. (With the pen knife a cross-section (as appropriate for a long DIN envelope) and bent up the corners. Punched the cardboard with a chisel and glued the leftover faux leather parts inside.) The camera comes in "iA mode" and set to "viewfinder" in the pocket and is always ready to go.
