Here is an excellent setup with the standard 80mm f2.8 CF, late style waist level, and A12 Back. The waist level makes the camera smaller and lighter and leads to a more contemplative style of photography. You look down, like reading a book, rather than holding the camera like a gun. Everything works perfectly, the shutter is strong and accurate, the winding is like butter and the lens has smooth focus and clean clear glass. The back has a good light seal. The numbers match. The camera comes complete with the lens cap and dark slide. This is a nice one.
