I consider trying to use a Fuji GX680 magnifying hood as a WLF on my Contax 645 but can find no specifications anywhere that indicate the dimensions of the base of this Fuji unit, width and length, which I guess is about the same/slightly bigger than the dimensions of the glass viewfinder prism on top of the GX680. Unfortunately I donīt have a GX680 so would be happy to hear from anybody who can recall or guesstimate the dimensions of the glass viewfinder prism on top of the GX680? Maybe 6x8cm or...
