  3. Re: Filter size of Carl Zeiss Jena Apo-Tessar 60cm F9?

    Thanks for all the replies. Bernice’s note about the aperture slots may solve for what I’m working on. Mine does have the slot so I may be able to make a disk filter and use that. If that fails,...

    Can anyone explain the differences between the D250, D375, K250, K375 etc? Looking at the website, it's not very clear what the differences are.

    Another question. Regarding the power supply, is it a standard corded adapter that plugs into the wall or does the power require more complicated set up?
