  1. Re: Can you tell me anything about this lens please?

    Looks like a generic English Rapid Rectilinear. Should be a decent lens, if a little slow at f/8. Very likely original to the camera.

    Re: Velostigmat for 8x10

    I don't know why, but for a string of focal lengths Wollensak made the Series II in half-inch increments, 14", 14.5", 15", 15.5", and 16". There's also a 19" and a 19.5".

    If you really want the soft focus feature, you can remove the front engraved ring and put a spacer behind the front element to move it out farther, then reassemble. Moving the front element out is...

    Re: question for you wet platers

    Keep in mind Watkins used Rapid Rectilinears (maximum aperture f/8) for his smaller plates. He only had one lens for his mammoth camera, a 16-inch Globe lens, which was only sharp between f/36 and...
  6. Re: Using a Neutral Density Filter on a Rear Lens Element

    Then you might try getting a step-down ring of that size. Make it a big step and you'll have room to put some screws through it to attach it to the lens board.

    "Budget" is a pretty nebulous specification, meaning "whatever I find cheap", so it could be anything. The OP could find a "budget" Cooke Portrait Lens for under $50.

    Re: Banding in Negative

    Increased development along the edges is often an artifact of uneven agitation. I'd guess you're getting more aggressive agitation, hence increased development, along those edges.

    In lieu of finding one, you can always use the old ring-clamp trick. I cut down sewer connecters from Home Depot so I don't scratch the barrel.

    The 12-inch will still cover 8x10 at full soft. The 9.5-inch Velostigmat Series II will also cover 8x10 at infinity (barely), but not at modified full soft.

    Yes, the modified lens is indeed a bit shorter in focal length. My 12" (300mm) Velostigmat Series II goes down to 9.5 inches (240mm), so about an f/3.6 at full soft. For that reason, it's good to...
