    I'm old enough to remember that... and the ad too:

  3. Re: What kind of lens bends an image without distortion?

    Sinar used to offer a front-surface mirror (catalog no. 538.11) that could be mounted in a Sinar 4x5 standard and positioned on the rail in front of the lens for just this purpose.

    Re: Schneider Apo-Symmar L?

    Good point, that's surely an important part of it. But both Schneider and Rodenstock specified smaller maximum apertures for their 480's when supplied in Compur or Prontor rather than Copal (f/9.4...

    Re: Schneider Apo-Symmar L?

    Nitpick: in addition to the 480, which as usual is constrained by the shutter (down to 56 degrees), the 300 is specified for only 72 degrees.

    Re: Looking for 5x7 macro lens recommendation

    Mike, if you're looking at process lenses, the 150 mm Computar will also easily cover 5x7 in close work. I use mine, stopped way down, as a wide for non-close work with whole plate.
