  1. Re: Optical diagrams of Pinkham and Smith lens?

    The Verito and Veritar weren't "of the Periscopic (two single meniscus elements) type." Both had a cemented achromatic doublet at the rear and a single meniscus up front.

    P&S went through several...
  2. Re: pros/cons of two different lenses at the same focal length?

    Technically, it would work, but the image at 360mm would be waaay out of focus. If you were at a very small aperture, that would bring it back into near-focus somewhat-if-you-aren't-too-fussy, and...
  3. Re: Westen Photographic Historical Society annual Show and Sale

    I'm at this show every year doing free tintype portraits, and KEH hasn't been a problem for us. Small dealers know that the private buyers attending the show will pay a lot more than KEH. Instead,...

    Re: Confused by lens math

    That's the culprit. The Copal 3 has a smaller maximum aperture than the lens' original shutter, so your f/5 measurement is right. the good news is after using the Verito a while, most people seem...

    It should be pointed out that at Saint Ansel's suggestion, John Schaeffer updated the books to their latest incarnation, a two-volume set. It's been used as the text in a lot of college photo...

    Re: Post y'ur Pinkham & Smith Pics!

    The Verito came in around 1913, and stuck around through the late 30s at least, and continued as the Veritar through the late 50's. By comparison, P&S was a flash in the pan, going through a number...

    I use both large and small apertures, from f/3.5-ish to f/32-ish, and often use movements. As a rule, the more open the lens, the more important it is to have movements to push that shallow depth of...

    Re: Lens help needed (8x10 wet plate)

    Then a 14 to 16 inch lens. As fast as you can afford. An f/4.5 Tessar would probably be the most cost efficient, although you might consider some of the projection lenses (Beseler, Buhl...)

    It won't prevent light leaks in the holder itself, but it helps keep light from creeping in through any space between the seated film holder and the back.

    First, what size plates will you be making, full 8x10, whole plate, or 6x8? Many wet plate photographers use converted 8x10 film holders, which are cut for a smaller size. (I like 6x8, because you...

    Re: help choosing portrait lens?

    The Velostigmat Series II is a fast (f/4.5) Tessar. I'd recommend a 9.5-inch with the soft focus uncorked. For use with strobes, either a Packard shutter, or look for one in a Betax and switch the...

    Re: 12" Goerz Dagor?

    Later coated Dagors are the best performers and worth the most. Pricing is iffy as there were many iterations of the Dagor, and of Goerz itself, mostly overlapping.

  28. Re: First and second lenses for new 4x5 shooter

    Start with a 150mm. Everybody needs a "normal" lens. Later maybe buy a 90mm. If you're going to have two lenses, 135mm is awfully "inbetween", unless you add a 75mm. Be open to letting a view...

    Definitely. Is a small aperture and wide field enough to correct astigmatism? Or does that combination make astigmatism irrelevant regardless? Or did engraving it on the lens just sell more lenses?...
