First I thought this was a sort of zoom-extender. But I guess it is rather a 2x-extender incorporating a variable extension tube.

I have a project where I need to shoot a flat shiny surface about 1x1 inches. I need good distance from the subject to light it well and control reflection. I can use either a medium format hasselblad or a 4x5 Linhoff Technika. For the 4x5 it was suggested that I reverse mount an enlarging lenses for extreme macro photography. Does anyone have any suggestions for the Hasselblad or linhoff to fill either size film

For starters, with the Hasselblad, we would need to know which lenses you have. What good would it do to tell you the extension tube size for a lens that you do not have?

Similar data for the Linhof.
