Keith, where did you get your RZ lens mount for view cameras? I would love to try your methods with my 110 2.8 on my 4x5 (Sinar) and 5x7 (Kodak No. 2).
I made the mount, it was very easy.
I glued a body cap to a lens rear cap, back to back. After that cured, I drilled out a 1.75" center hole through both with a hole saw. Placing the rear cap on the 110 lens, you will be delighted to find that there is now a 1/8" ridge (near my thumb in photo #3, attached) between the lens' fastener ring and the homemade thing. The ridge grabs a 1/8" lensboard when you rotate the ring. All you do is drill out a 3.75" hole in the lensboard and then you have an easy way to put any rz or rb lens on your view camera. No screws, no nothin'... just rotate the ring to put it on or take it off.
Honestly I didn't make this adapter to use it with a view camera. I made it to adapt rz lens to an rb. But then after an hour of work I realized that simply removing a pin on the rz lenses allows them to go on the rb :rolleyes:
Erie Patsellis has a fancier approach that involves removing the lens mount from an rb (cocking mechanism and all) and putting that on a lensboard. That method allows you to cock and fire the leaf shutter on the rb lenses. In my case, I just hand shuttered. But I have an Erie gizmo too. I am just thinking that I might be able to electronically fire the RZ lens if I put my mind to it. Another project for another day. Anyway, I suspect that the rb lenses generally have more coverage than the comparable rz lenses. The 127 KL, for example, seems to cover 4x5 better than the 110.
Oh, you can do the same hooplah with the mamiya 645 lenses... or small format lenses... or whatever brings you joy. Just for kicks I have mounted the 80/1.9 and the Nikon 50/1.2 in this way.
Have fun!
