    Distance to FP for 150 Xenar infinity focus

    I have a 150 Schneider-Kreuchnach 150 f5.6 lens and matched focusing cam. Because it's so hard to find any horizon more than 100 yards away in this area, I've been unable to calibrate the lens and would really like to use it on my Horseman. Does anyone have the calibration mark number for infinity focus?

    Greatly appreciated, and if I'm in the wrong forum, I apologize. But after several failed attempts to get the lens calibrated, I'm at my wits' end, and I want to use the camera for more portraiture and less landscape. I have it calibrated for the 75 and 105.

    Instead of looking for a horizon why not use the sun?

    The sun is very hard on the eyes.

    Use a full moon. It's a sunlit object, by definition.

    If you believe you can, or you believe you can't... you're right.

    Duh! Those scientist types say the moon is a long ways off, but I heard it was just the next county over. Thank you!
