    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.

  8. 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...
  9. Re: "Barn Find" Brass Barrel Lens Mystery!

    Not much to go on. Is it a Petzval or a Rapid Rectilinear? A cemented rear element is a Rapid Rectilinear, air-spaced is Petzval. Any engraved numbers or markings on the rear rim (aside from the...

    Re: Are all Goerz Double Anastigmats Dagors?

    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?...

    The Hypergon is a symmetrical two-element design. I don't see how it could be corrected for astigmatism.

  14. Re: how to avoid the lens shade / compendium in the image

    If the vignetting is on one side of the negative only, I'd suspect bellows sag over the shade. If it's on both edges, yep, the shade. But with the narrow angle of view of a 500mm on 4x5, I'm...

    Agreed. Raw resolution is only one factor, but often still an important one, and it's the one that impresses most people, perhaps because it's the one that can be expressed by a simple number. For...

  20. Re: Which shutter-speed is park-position when not in use?

    The lowest tension on the spring is at "T" or "B", uncocked. I prefer "T", ready for focusing.
  21. Re: What kind of lens has aperture scale in mm?

    The difference being?

    I think if an f/stop is the ratio of focal length to aperture diameter as measured through the entrance pupil, that would be both the actual and the effective f/stop. But...
  22. Re: What kind of lens has aperture scale in mm?

    It's calculating your actual f/stop, not compensating for an incorrect f/stop.

  24. Re: What kind of lens has aperture scale in mm?

    One of the basics of photography: the f/stop is determined by dividing the focal length by the aperture's diameter as measured through the front element, (aka "entrance pupil").

    I figured you'd know it already, Pere, but some here may not. Your comment was just the perfect lead-in to my point.
  29. Re: What kind of lens has aperture scale in mm?

    That would be the trick when using it with the casket set as mentioned by pjd. Different front cells would render slightly different sized effective apertures from the same raw aperture.
  30. Re: What kind of lens has aperture scale in mm?

    The only math skill required would be simple division, and you'd only need to be in the ballpark for practical purposes.

  31. Re: Can you diagnose this patchy look of the lens?

    By the serial number, it's a late 1940s/early 1950s lens. Coatings of that time were softer and less well-bonded to the glass, so were more susceptible to mechanical and environmental damage. The...
  32. Re: Can you diagnose this patchy look of the lens?

    Could be damage to the AR coating, which won't clean off but won't affect the image much, if at all.

    Re: Lens Not Focusing, What is the Cause?

    I'd start by checking the focal length of the front and rear elements separately. The lens being a fairly symmetrical Plasmat, each should focus at about 240mm. (Tell me if I'm wrong, folks;...

    It's the internal air-glass surfaces that are most critical. Missing some coating on the front element means a bit of light will reflect back outwards into the world, have very little effect. On...

  36. Re: Dallmeyer or Vitax diffuse focus in action?

    Dallmeyer's original intention with the "soft focus" feature was to increase depth of field, not give a softer image. It kinda did, sort of, in a way... But the by-product of having a softer image...
