    Re: 20x24 lenses

    If you're doing still lifes, the Tessar may well cover at close distance.

    Re: 210mm F5.6 Lens For 8x10

    The 210mm f/6.8 Dagor and Ilex Acuton f/4.8 215mm both cover 8x10, but not much more.

  4. Re: Part of vintage lens or vintage car or something else?

    I'd guess a front aperture for when using the Petzval's rear element alone as a landscape lens, though it doesn't look original.

    Re: Radioactive Lens Treatment

    I leave my Aero-Ektars on the windowsill of my studio, with the back elements facing out and the fronts covered with aluminum foil so they don't focus the sun and start a fire.

    I find a Dracula cape works well, plus you can scare away little kids who get too curious. (And I always feel more creative when speaking in a bad Transylvanian accent...)

    Re: 8x10 Wide Angle Lenses for Still Life

    At these bellows extensions on this format, the center filters aren't necessary. They're only needed when the center of the lens is significantly closer to the center of the image than the corners.

    Re: 8x10 Wide Angle Lenses for Still Life

    At close distances with extended bellows, coverage expands greatly. A lens that just covers 4x5 at infinity will cover 8x10 at 1:1.

    In my experience, very wide angle lenses perform pretty...

    Re: Goerz Dagor 6” f/6.8

    Don't know about Roversi, but Avedon used a Schneider Symmar-S 360mm and a Fujinon 360mm f/6.3 lens. Both would be considered pretty modern. 360mm on 8x10 is equivalent to 180mm on 4x5, so take...

    Re: Longest Wet Plate Exposure Times

    I don't like to go longer than 5 minutes (indoors) as the plate can start to dry and the image suffers. Knowing Sally Mann's work, I don't think that's as much of an issue for her.

    Re: 4x5 lenses: telephoto and portraiture

    Just for anyone who doesn't know, a telephoto design gives the angle of view of a longer lens at a shorter focusing range. So a 400mm telephoto might focus at infinity with around 250mm of bellows.
