    Will the lens on an anastigmat-equipped 3A camera like the ones you identified above cover 4x5 as the RR in the ball bearing shutter does?

    Among basic Anastigmats, the Tessar-type lenses have the least coverage of only a few percent over the focal length. So you can safely assume that any anastigmat with a focal length of 150mm or more will cover 4x5".

    3-A

    Thank you.

    I guess I don't need a third...but an anastigmat would be nice to have too...

    REALITY CHECK

    OK, I was happy to have gotten a 170 mm RR because of it's personality...but I just realized if I have a Tessar, the Anastigmat may have less 'personality' than the RR, and thus closer to redundant with respect to my Tessar-type, other than a little longer.

    Repro lenses are an obvious, and well known, exception to the rule. Anything older with "APO" in the name has a ihgh likelyhood of being a repro lens. The only exception I know of is the APO-Lanthar, which has more coverage than the basic Tessar. But that's not a repro lens, unlike the APO-Tessar...

    As an aside, my father gave me a camea yesterday: A Kodak Autographic 2A camera with B&L RR lens. And I'd promised I wouldn't "aquire" any more cameras this year...

    Seems to me, Ole, last report had you promising not to *buy* any more -- clearly, receiving a gift is entirely different. If your wife speaks good English, I'd be happy to explain that to her, too...
    Photography has always fascinated me -- as a child, simply for the magic of capturing an image onto glossy paper with a little box, but as an adult because of the unique juxtaposition of science and art -- the physics of optics, the mechanics of the camera, the chemistry of film and developer, alongside the art in seeing, composing, exposing, processing and printing.

    Anyone know what f.l. is on an Ansco #5 (4-3/4"x3-3/4" image, Kodak 103 or Ansco 10A/10B film)? - I suppose it could be same length lens, but looks older...I'll find out when it arrives.

    The shutter is one of those with the cylinder...pneumatic? I wonder how those survive the years...as well as Ball Bearing Shutters? Time will tell...

    I have a 135mm Tessar on my home made 5x4 camera which I got from an old 9 x 12cm plate camera. It covers 5x4 quite well and allows for some movements. Am I just lucky with this one?
