Feeling Adventurous? Creative? Wanta have some fun with your 4X5. Here's a challenge that will repay triple in fun.
This is like the one I used for the Dead Link Removed. But I won't guarantee this one is that wacky. They seem to have personality profiles of their own.
What I do with these is bore a hole that is a friction fit around the lens body, and then seal up the back side with some gaffers tape. F3 is smokin' fast though. You'll need a Speed Graphic with focal plane shutter I would think. It's about 51mm wide, so maybe there's a #4 Betax that could be made to slip over the front.
Problem solving is part of the creative process. $66 is no problem though! + shipping
