  1. Re: Have you had to pay hefty customs fees when buying from Japan?

    The most likely is that your previous purchases, like mine, came by mail. Couriers such as FedEx, UPS, DHL ... charge customs brokerage fees. I see this as dishonest and insist that my goods be...
  2. Re: Looking for thoughts/experience with mounting a big Dallmeyer 8" lens on a LF cam

    Thanks for the reply.

    My, you must be rich. Asking prices for long Super Sixes are well into 5 digits (USD). Have you considered getting an 8"/2.9 Pentac or a 7"/2.5 Aero Ektar? They're much...
  3. Re: Looking for thoughts/experience with mounting a big Dallmeyer 8" lens on a LF cam

    Don't be so coy. Tell us which 8" Dallmeyer lens you have. Name, focal length and aperture. If it is a Super Six, it might not fit a Compact 5x7's board. Unfortunately my references don't give...

    Mark, I have 203/7.7 Kodak Anastigmat. It has the same prescription as the 203/7.7 Ektar. Mine is in barrel. I have other 200 +/- mm lenses so haven't tried to find a shutter that's right for the...

    Re: Old scratched lenses, coatings, etc.

    If the lens is coated there will be a C with a W inside it on the trim ring. It should be coated. Large scratches can be filled with, e.g., India Ink.

    To find out whether the scratches will be a...

  8. Re: My first Lens. Symmar-S 6,8 /360 in a Copal 3 shutter. What next?

    Um, er, ah, if I understand these things correctly the lens board goes between the rear of the shutter and the retaining ring, not behind the ring. The ring's flange should butt on the board.
  9. Re: My first Lens. Symmar-S 6,8 /360 in a Copal 3 shutter. What next?

    Mark, I'm sure that, given your profession, you know that every lens has three focal lengths.

    There's the engraved/marketing focal length. There's the design focal length, i.e., of a lens made...

  12. Re: Just bought a Fujinon 135/5.6 W ( first type )

  16. Re: Schneider Tele-Xenar 240mm f5.5 shutter question

    Check the rear threads. #1 shutters are asymmetric, M40x0.75 front threads and M36x0.75 rear. In other sizes front and rear threadings are the same.
