The question in my original post is stated poorly, but basically I'm just curious if I can close the camera with the lens mounted.
Though, you raise an additional question... I've been leaning towards the Kalart rangefinder because it's adjustable to any focal length (as I understand). How quick is this operation? Are the Hugo-Meyer, Focuspot, Tower and any other RF's adjustable, or do they use cams?
In my mind, the ideal would be the ability to change between lenses at will and retain RF function. But I have a feeling that it's a little more involved than that. Sooo, do cams make this operation quicker? And what RF's have cams?
Is the Hugo-Meyer
