I'm experiencing some difficulties with mounting my Hasselblad with a Proshade on my tripod. I have a Manfrotto 3-way tripod head with one of those hexagon quick-release plates, and when I attach it to the camera it ends up fairly close to the lens. This becomes a problem as I mount it to the tripod, if I have the proshade attached as the little rail at the bottom gets in the way of the tripod head. I was wondering if anyone else has encountered this problem and how you solved it? I've thought about mounting the proshade upside down, but I can't seem to get it in position, it usually locks in place at angle, which I assume would cause vignetting.
