Soon I will have an Eastman View No. 2 5x7 and a B&J Grover 8x10. All my usable lenses are in Sinar DB mounts, however. Now I have not held the cameras in my hand yet, but I figure there may be some way I can adapt my Sinar shutter, a carrier frame, and the lenses to the big cameras, so I retain normal control of the lenses. Unfortunately, only one of the lenses is DBM, so I would need to mount the shutter and carrier frame for sure. I am interested in hearing from people who have done a similar mod to allow use of their DB lenses on non-Sinar cameras. Just throwing ideas around and looking for examples. Thank you in advance.
