  1. Re: 75mm Super Angulon 5.6 - Lindhof Master Technica - SOFT EDGES

    One way to see if your lens board is causing interference would be to measure the overall length of the lens mounted on the board, then take it off the board and measure again...

    Re: Premium for black Copal shutter?

    I have not... I should have clarified - I was referring to the Copal Press shutters. Although the Prontor professional is self-cocking, would it be regarded as a "press" shutter?

    Re: Premium for black Copal shutter?

    The thing I don't like about the Press shutters is that when the lens is open using the preview lever, the aperture is automatically set to full open. This means you can't stop down to check your...

    Re: Caltar Rodenstock 135mm aperture scale

    For many shutters on large format lenses there are no limits on the aperture lever's movement. It's normal for the shutter blades to be just visible at the large opening, and for the knob to move...

    One thing you can do to reduce the load on the Jobo's motor is to rotate in one direction only. Flip the little white reversing arm by the drive gear out of the way. I use mine this way with Expert...

    Re: Linhof Technikardan 45S repair info?

    Hi Bibbt,

    The way the slide mechanism is designed, it needs to have some play in it to let the standards slide freely. It could be that the play you're seeing is how it came from the factory. The...

    Re: Wista 45VX/RF/SP bellows draw and idea

    I don't have any problem closing the camera - the front standard is definitely hitting the hard stops inside the body, as opposed to the bellows preventing it from going all the way back.

    Re: SEIKO shutters, what size do they come in?

    Seiko had a shutter size with slightly bigger diameter cell threads (not sure if it was both front and back) than Copal 1 - both the older Fujinon 210/5.6 and 250/6.7 lenses came in that size. Later...

  29. Re: Math: Calculating distance scale based on focal length, FFD, helical travel

    I don't think you need to worry about nodal points too much. You're calibrating infinity focus by eye on the GG, and then you want to mark various distances closer than infinity. Using the formula...
  30. Re: Math: Calculating distance scale based on focal length, FFD, helical travel

    I've used the thin lens equation to calibrate helical mounts. Solve for image distance i. Then, i - focal length = incremental distance the helical needs to move from focus at infinity.

    The Seiko shutter may not be compatible with a Copal 1. I've had a couple of these lenses with Seiko shutters and the threads were different (larger outside diameter and coarser pitch) than a Copal 1.
