   A way of using barrel lenses economically is to adapt a
single shutter so that it can be used with a variety of
lenses. I have an Ilex No.5 Universal shutter fitted so that
it takes a lensboard. I can mount any lens on this shutter
provided it does not need a larger clear aperture.
   One can do the same thing using a large Packard shutter.
Mount it on a lens board which has an arrangement for using
smaller lensboards on its front. I have a large number of
lenses mounted on Speed Graphic 4x4 inch lensboards. These
can be used directly in older speed graphics and some view
cameras but I also have adaptors so that they will fit all
three of my view cameras plus the Ilex shutter.
   Both the Ilex and the Packard shutter are limited in
speed selection. The Packard is essentially one speed and
time or bulb. The large Ilex works from 1 second to a marked
1/50th, but its really on about 1/35th. There are a couple
of other large shutters available: the largest Compound
(probably the best of the bunch) and the largest size
Wollensak Betax. These last are not often seen but IMO are
better shutters than the Ilex. I certainly agree that most
barrel lenses are not worth the cost of adapting them to
shutters. If you have one you think _is_ worth it try Steve
Grimes shop at
