  1. Re: "The big two" - Please tell me about your japanese lenses!

    This is too confusing unless I limit my answer to 4x5 lenses. However, I use several of these with 5x7 and 8x10, too.

    Fujinon 65, 135, 180, 450. I like all these but the 65 and 180mm don't see...

    Re: DOF on 8x10 vs. 4x5?

    It's all very confusing. Thing to remember is longer lenses reduce apparent DOF and there is no winning.

    Same f/# and same lens gives same DOF. Lens doesn't know how big your image is. ...

    Re: Sheet Opal Glass sources ?

    At 420nm (still in the visible, surprised they call it UV), you're in-band with flash opal glass, however, in-band is only 35% transmission. That's almost 2 stops down.

    What is the heat issue? ...

  12. Re: How to decide for a set of three lenses for a Linhof Technika IV

    Ig, the 135mm is a wonderful choice. I'm not a big fan of the 150mm on 4x5 either, but the 135 is very nice. Plus, if you really need the 150mm, just crop 11%. The 135 is nice, too, because they...

    Just try it. I make 5 liter batches and store it in 500cc bottles. I test each one before I use it. Never had a bad one.

    Given how you haven't mixed the dry chemicals yet, it should be fine.
