Omega D2
I'm setting up an Omega D2V for the first time and a few things aren't
self-evident or explained well in the manual. The one that immediately comes to mind is how do the lenses mount. Do I completely unscrew the two knurled screws, place the flat lens boards there, and then replace the knurled screws? And, what about the lens cone? How does it attach to the lens stage? Thanks in advance Jim |

The lenses mount on the round flat lensboards.
The lensboards mount to the lens cones using either knurled screws or machine screws. Since the D2 bellows is so short the cones for different lenses are different sizes, longer cones for longer focal length lenses. Harry Taylor of Classic Enlargers says that 105mm or shorter lenses are mounted on flat boards but I have cones made for my shorter lenses, too. Find an online copy of the D-2 setup guide if you don't have one in hand. It will aid in sorting out which lens uses which lens mount plate and cone. Any machine shop can make new lensboards, good if you have odd-ball optics that don't use Leica thread. Recessed lensboards also exist for short focal length lenses: 40mm, 38mm, 35mm, 28mm, 25mm, these lenses are useful for larger magnification when printing half-frame 35mm, 110 and subminiature formats. Harry Taylor http://www.classic-enlargers.com/ and KBH http://www.khbphotografix.com/omega/ have parts. Harry actually has new parts made for him. D-2 and D-II cones mount with a twist. You push up against spring tension and twist to mount. Twist the other way to remove. D-3 and D-4 cones push straight in. Recessed lensboards won't work on a D-3 or D-4. -- darkroommike ---------- "Jim Worthington" wrote in message m...
