This page describes my effort at having a Rollei lens adapter mounted to an
Arca Swiss 171mm x 171mm lens board for 4x5. I chose the larger lens board
for this project as there's a chance that I might want to use the adapter with
my Schneider 180mm f/2.8 lens for Rollei so I could use a little rear tilt to
make adjustments to the plane of its tiny zone of sharp focus. As that lens
is pretty heavy and would be all on one side of the lens board, I thought it
better to use the larger board and have a little more leverage helping to
control the stress at the interface points between the board and the format
frame. As shown in the pictures below (Click on them for larger versions.)
the lens adapter has the same V groove for mounting to the X-Act II as does
the panshot. After the panshot project, this one was pretty simple. SK Grimes
did an excellent job of turning down the outside of the groove, putting threads
on it, making a nut and mounting it through the front of a flat lens board with
a big custom hole they made in it. I didn't request threads on the other side
of the nut for a filter, since I've already got one on the panshot and likely
won't be using the adapter without the panshot. It wouldn't be hard to make
such a nut in the future if need arose, though. My mind was at such ease about
this project that I forgot to take photos of the result when I was last home for
a few days. When I'm home next, I'll try and remember to take some photos of the
Ok, here's the adaper installed in the board, front & back and on the camera.
Having the ability to move the smaller 16 megapixel square sensor on the Ixpress
around the image circle of the Schneider 40mm f/3.5 Super-Angulon lens is a
beautiful experience for me.
