   If you have a large shutter like the Ilex #5 Universal
you can have an adaptor made for it to take small
lensboards. That way you can mount any number of barrel
lenses on the same shutter. I have a #5 set up to take 5-1/4
x 5x1-4 boards, the size use on 5x7 Agfa cameras and also I
think on 5x7 Kodak 2D's. I also have a board this size with
an adaptor for 4x4 Speed Graphic lens boards. I use the
Graphic boards for all lenses which will fit on them and the
larger boards for larger lenses. Actually, you can make the
same sort of rig for a Packard shutter. This is economical
since you can use the same shutter for any number of lenses.
I have adaptors for the 4x4 Graphic boards for four LF
cameras and can use them in a total of eight cameras.
Another neet item is an iris clamp but they are hard to
find. These clamp around the barrel of the lens mount. The
only problem is that they are not the most secure type of
mounting and can damage threads if tightened too much. I
have a small one on a 4x4 board I use for mounting enlarging
lenses for macro work. Its easy to mount the lenses backward
by clamping the outside of the front. The advantage of this
is that the stop ring is exposed. Iris clamps were never too
common used but, like so much other stuff, seem to have
become rare now.
