  1. Re: Moderate wide + shallow DOF lens recommendations?

    I think a 180mm Heliar would give you the closest look to the Pentax 105mm with only a third stop difference in DOF. You can get them either in barrel and use the Sinar Copal shutter or in a Compound...

    Re: Seiko #00 shutter

    Some Horseman Topcor lenses were put in these shutters, I have a 90mm that I can't swap the shutter with other lenses because of this and the fact that it has a different thread size.

    Re: Help to ID this lens.

  14. Re: 150mm f/5.6 Rodenstock Sironar spacing info?

    The raised ring you mention on the copal shutter sounds like a plastic trim ring, it pops out and your lens should fit fine in the newer shutter.

    The Komura telephoto lenses have flange distances of 221mm for the 400mm f8 lens and 258mm for the 500mm f7, the 400mm has a 190mm image circle and the 500mm 210mm.
