ron_lawrence1 Posted July 25, 2000 Share Posted July 25, 2000 I currently have two different focusing loops that I use on my 4X5 view camera (Toyo 4X & Eschenbach 8X). I have recently gotten a Acculight light table and I'm using the same two loops to view transparencies on this light table. What I have noticed is all transparencies are very slightly soft when the loop is placed on top of the transparency. When I raise the loop up off the transparency approximately 1/16" for the Eschenbach and 1/8" for the Toyo, images are tack sharp. What's going on? Do I need to purchase a special loop for viewing transparencies on a light table? Thanks! Link to comment Share on other sites More sharing options...
dmin-99 Posted July 26, 2000 Share Posted July 26, 2000 They must have focusing helicals. They appear to be adjusted for reading the opposite side of a groundglass (which is correct for focusing - although they should both be "off" by the same distance on the transparancies if they're both adjusted correctly for your eyes). You'll have to refocus them to view transparencies (twist the ocular counter-clockwise). Link to comment Share on other sites More sharing options...
ron_lawrence1 Posted July 26, 2000 Author Share Posted July 26, 2000 One thing I forgot to mention that may be an important issue. In my older age I'm now wearing Varilux progressive focus glasses. Lining up you glasses on the loop eye-piece for sharpe focus can be a real hassle. Link to comment Share on other sites More sharing options...
