Set up a test today. I'd made modifications to the loading end springs on the back, seems tight enough. Set up a closeup of the Konica, more than 1:1 on the 18x24 UM-MA. 20" of draw with a 5" lens. Guessed at reciprocity compensation, got in the ballpark.

So, the bad news: The holder seems to have a small leak on the slide end. Not sure what to do about that. Need to try the other side, and other holder. Hopefully the rest are better.
