  1. Re: Where should I send my Copal shutters for a CLA?

    I have used both Zack's and Bob Watkins. The latter CLA'd my Copal 3 earlier this year. I must have gotten lucky -- it was back to me in less than a week.

    Re: Depth-of-focus problem, enlarging lenses

    Maris, thank you for your contribution, which is very helpful indeed. In fact, my 4x5 carrier has a custom inset of white plexi in the top window, for use with a hand-penciled or -marked masking...

    Re: Depth-of-focus problem, enlarging lenses

    Bob, that's interesting! So, I should be getting calculations for the 135 instead -- I am, of course, assuming that the depth-of-focus in the enlarging lens is at the back, as it is in a taking lens,...

    Re: Depth-of-focus problem, enlarging lenses
