    Re: Lens Result Question

    Well there you go ...

    A lens that is designed to have a curved field. You (should) learn something new every day.

    I'm not a betting person so I'll bet there isn't such a thing in 35mm photography !!

    Thanks Mark !

    Perhaps you should re-shoot when the wind isn't blowing.
    And as for focusing on the house number, I can't read it. It looks out of focus to me. But the tree branches are blurred whereas the roofline behind them is [relatively] sharp.

    Do you shoot flat field subjects like a newspaper page on 35mm or 3 dimensional objects like people or landscapes? If the latter then the lenses corrected to reproduce 3 dimensional objects on a 2 dimensional piece of film are corrected for curved field reproduction.

    You might look at the specs for the Minox subminiature Cameras, not the Japanese versions. The German and Latvian versions have a fixed 3.5 aperture lens and a curved film plane. They did excellent reproductions of flat objects like documents. And this worked with a lens fixed at wide open!

    I'd bet some of the newer Lomo AF (Artsy-Fartsy) lenses like the "Petzvals" and "Daguerreotype Achromats" made for 35mm have curved field. But among main-stream lenses, yup, by the time 35mm became a legitimate format, lens design had pretty much matured past such things.

    Looks to me like your developer was developing and your veritar was veritaring. Like the Verito, the Veritar becomes a lovely soft focus 17" lens when the front element is removed.

    I imagine it loses some speed doing that?

    Yes, of course. Longer focal length, same size hole. f6 becomes f10 ish.

    Yup. One thing about math. It never changes...

    But you know, I think I pretty correctly spotted a pretty off-the-beaten-path issue without knowing what lens was involved. I think I deserve a prize of some sort.

    Really, this forum needs prizes. And I want one. I don't care what it is, I just want one.
