I use a Wista 45SP metal field and have a question regarding Wista's predrilled lens boards. Why is the hole offset toward the bottom of the lensboard? With t he camera back removed, the rear element of the lens is displaced off-center by approximately 1/2 inch. Not only does this effectively reduce my front rise (on e of the more valuable view camera movements), but it also prohibits closing the camera with certain lenses attached that would otherwise fit when I use a board with a centered hole. What gives?
