During a playtime session, I held my 45/4 lens over an open lens board on my Sinar 4x5 view camera just for grins and giggles. To my surprise, the image circle of the 45/4 lens almost covers the 120mm portrait distance of the 4x5 format. The angle of view seen on the ground glass was significantly wider than seen in the 6x7 view screen.

My question: has anybody any experience with the various P67 lens adapters?

I am thinking about the possibility of adapting the 45/4 lens to either a Copal #3 shutter, or a Packard shutter. One of the ideas that comes to mind is simply mounting a rear plastic lens cap in some fashion to the shutter or lens board. This would keep the rear element as close as possible to the shutter.

Mounting to the Copal #3 shutter is the best solution, but I have concerns that vignetting might be a problem, due to the thickness of the shutter/adapter combination.

I am working the other angle, adapting odd lenses to work on my pentax 67... So far so good, I mounted an antique lens liberated from a decomposing 620 folding camera. The lens is mounted to a rubber "plunger" which in turn is mounted to a body cap that I modified (thanks dremel tool). The rubber "plunger" allows me to push/pull the lens to achieve relative focus, now the fun part...I can get enough shift and tilt to make things really interesting. Downside is my arms and hands are killing me...It's a lot of work but very cool toy/Diana camera look with the dependability of my pentax, and I can proof by moving the lens over to my Polaroid body to reassure the art director/client(and myself).

woops i got my e-mail wrong on the above reply Sorry I got off on a tangent, let me know how your project comes along. I might have to try something similar myself. I have made lens boards out of 4-ply black solid core matte board, they worked quite well but never had the weight of my 45/4...My first thought is let the stobes be my "shutter", pull the slide the fire with a remote trigger then replace the slide. good luck.
