    Re: Apo nikkor 760/11 at infinity

    I have one of those. Got it put into an ilex #5 shutter by Grimes. Superb performer. On pics of a large tree, I can see the veins of the leaves with a 10X magnifier. I use it on a Calumet C-1 8X10. I...
  2. Re: Changing shutter speed on a Ektar 127mm f4.7?

    The front of that shutter comes off easily. The speed ring that turns has dried up grease. Take it off, clean it and the surfaces it contacts, alcohol is fine. Then lube with a very small amount of...

    Re: Calumet C400

    I have the Calumet CC-400 (normal rail), CC-401 (long rail) and CC-402 (short rail). I keep seeing reference to CC-403, 404, 405. What are they?

    Re: Fun with Acetone

    I have not worried about the relative rotation. 3cc is enough for many lenses, you only need 1 drop.

    I have usually used MEK. It may take a couple of weeks. When done, the elements will slide apart, maybe slowly since the balsam is not gone yet, just softened. Clean up with the acetone and a soft...

    Re: New to LF...

    In Death Valley landscapes I use 203 or 210 most of the time. I have found, in 10 years, one scene that wanted 90, and one that wanted 65. But several that wanted 135 or 360.

  9. Re: No 'bulb' mode on my new Compur 3 shutter

    It is common for a shutter to get stuck if not used for a long time. The lubricants dry up. So one gets used to operating a shutter a few times to work the lubricant around and un-stick it, even to...

    Re: Calumet CC-400 lens board question?

    There are boards that fit that camera, available from Calumet and Ebay.
    It is best to have a board for each lens. Makes changing lenses much faster, and saves wear and damage to the lens threads.

    Re: Stupid Question - Wide Angle Lens
