I did see a couple of Flickr posts where users have mounted the full camera onto a DSLR. That method certainly is a conversation starter. I prefer my method though for several reasons: you get to use the 100% of the lens diameter which will be softer but faster. Using the full mounted camera method means you keep the stock lens mount which yields a slower f/11 with "better" IQ. In this case the "quality" objectives is very subjective. Mounting the old meniscus lens in a donor lens (with glass removed) means you have easier focus and handling. The lens looks more "normal as well". I find using the donor lens focus helicoid with one of thee possible M42 extension tubes gives me all the focus options I need.
I am back from a quick east coast trip so I am planning on doing more tests with black and white with some portraits etc...
I've won a macro bellows (Nikon F mount) off eBay to try mounting one or more of my medium format folding camera lenses. I should be able to start out with a Nikon to EOS rear mount, and Nikon body cap to mount the lens in. Quite bit more awkward than your lovely lens barrel solution, but I have the option of mounting various lenses. At least that is the hope! I just wish I had swings and tilts, and especially shift. Perhaps a subsequent project.
I used this lens at a recent wedding in British Columbia. Results can be unpredictable but nice in its own way. I made sure to back up these shots with "regular glass..."
