  2. Re: Horseman 45FA/45HD - lenses longer than 210mm. with this extended lens board?

    This extension board may be used only with Copal #0 and #1 shutters. Plasmats are usually in Copal #3 or #3S shutters, making them unusable. Lenses like the Fujinon A and Nikkor-Q and M lenses are in...

  9. Re: How to open the shutter of Fujinon WS 150mm f6.3?

    I don't have a 5B-S shutter at the moment, and what I describe is based on the 5A. I believe both shutters operate in the same way.

    That is not how you use the shutter.

  20. Re: What lens to get for most shallow depth of field on 4x5?

    Some projection lenses will also work - Heidosmat 150mm f/2.5, Buhl 200mm f/2.5. You'll have to figure out a shutter mechanism, though.
