Letus35 Flip Enhanced Back Focus Problem

[Tomiger RoPort]

Well, I came to the conclusion that my adapter needs be adjusted for back focus issues. When I would set my lens to infinity, I did not have sharp focus the most far away objects (such as the clouds). I talked to someone from letusdirect through email and basically he said to just adjust the ground glass' position on it's slider. I discovered that when I moved my actual lens mount forwards (further away from the ground glass), I would achieve the correct back focus. So I knew I had to move the ground glass backwards on its slider. I opened the adapter and to my dismay, the ground glass is as far as it can go backwards on the slider. I am kind of lost now as to what to do. The way the nikon mount is on the letus flip, it will not be secure when it is moved further out. Any suggestions or insight onto something I'm doing wrong?

you can actually (very gently) push the three pegs the ground glass is supported on back in lieu of the "slider" - my measurement is 6.5mm from back of ground glass to front of Lex housing for my lens mount to be flush and infinity to be correct. I was given direction by Letus Direct - they may wish to advise you further but in reality, it wasn't that big of a deal to adjust and getting into the actual LEX, I was even more surprised as to how well it's built.

alright thanks, I'll try that now. Going to have to wait until morning to check the infinity focus though.
