I discovered this morning that my Computar 240, the whole thing in the barrel configuration, fits directly into the front of one of my old Ilex No. 4 Acme shutters. This could possibly be
attributed to the fact that the Ilex is accurate, but well used, so the threads are a bit sloppy.
However, it is securely and squarely mounted so I am wondering.... is there any reason that I
cannot use the Ilex on it’s board mounted in the usual way on my 7x11 as a behind the lens
shutter for the 240 Computar? The lens does not seem to interfere with the mechanism of the
shutter and as the maximum aperture for the Ilex is 6.8 and the Computar is 9 I am assuming
that I can employ this combination using Ilex wide open and setting f-stops with the iris of the Computar.
I am most likely missing something screaminlgy obvious as to why this will not work, could
someone please enlighten me as to what that is? However, if there are no complications I just
saved myself the necessity of acquiring a Copal 3S for my Computars......
Cheers & Thanks!
