Lack of focus

I'm still in the single minded pursuit of a way to put my screw mount lenses on the Hasselblad. It must be done! I can hear you, "Tanster, why would you want to put 35mm lenses on a medium format camera?!" It must be done!

"But aren't the 35mm lenses too small?"

Maybe, they are.

What's going to happen? Will the light reach the film adequately? Will I have to place the lenses too far from the film to be able to focus through the viewfinder? Come on, I need answers!
