After diving into the LF + old barrel (soft and hard) lens craze I ended up with several really huge chunks of glass. In order to test these I quickly constructed (stiff) cardboard lensboards and got the lenses onto a Cambo 8x10. After testing them all and then buying another (Velostigmat with diffusion), I wanted to move forward to settling on a lens or two (or three!) into shutters. I got rather depressed to see the solutions required either a) several packard shutters (one for each lens?), b) a Sinar shutter adapted to the Cambo, c) big expense of finding shutters and having SK Grimes (or others) create adapters for shutters
Yesterday, remembering something I read here (somewhere) about mounting a shutter in front of a lens. I had another Cambo body with a matching monorail to my Legend and put an Ilex #5 shutter (on a board) onto another standard with a bag bellows attached to the backside. I put this entire standard in front of the "Velo" lens using the bellows as a makeshift compendium and used different shutter speeds to run an exposure test. I was able to use 1/2, 1/5, 1/10, and 1/25 without any problems... without the bag making a lightproof "lens-box." The Ilex shutter's hole barely covered the Velo's front diameter, but it's not big enough for my big Tessar or Apo-Nikkor (lenses I want to keep).
I suppose I could just get a new Packard #6 Synchro and fill all my needs, but I might want an even faster shutter speed. Does anyone else use this kludge fix to the barrel lens problem?
btw, I'm a recent graduate of the "patented" Galli shutter system, so this was a nice upgrade:D
