    Fixing large frame space on Koni Omega Rapid 100?

    Hi,

    I got my new toy yesterday, a Koni Omega Rapid 100, and shot a roll and developed right away to check if it worked. Which it did. BUT the spacing between the frames is a bit too large. I only fit 9 and 1/3 frame on a 120 roll.

    The space between the frames looks nice and even along the whole strip of film, it's just too large.

    Any suggestions for an easy/cheap fix?

    I did some math and I would need to shoot well over 50 rolls to justify the cost of sending the camera back, over the cost of just getting 9 frames per roll instead of the intended 10. And considering my GAS I would be surprised if I pass 20. :-)

    Anywhere I can buy a CLA'ed or working film back for the camera? Everything else seems to work fine.

    Good Morning, Wilper,

    The only real weakness of the Koni system is in the film backs; irregular or incorrect spacing is not too unusual. Using a gentle film-advance approach can sometimes help.

    If you're using B & W film, nine-frames-per-roll isn't a bad way to go anyway, since getting a tenth frame on a standard 8 x 10 contact sheet is a problem.

    Konical

    If nothing else helps, there's always repair, this one is DIY style:

    I have the opposite problem with my Koni - occasional overlapping frames. If you can, get it get repaired, if not you just have to get to know it. I pay close attention to the way I advance the film (or slam the hammer, as I sometimes think of it), and I've figured out that a firm but slow pull works for me. For non-DIY repairs, Greg Weber <gweber@webercamera.com>, is the man for Koni-Omega. He's also very reasonably priced. Good luck - these beasts make incredible images!

    Yes, I've had 2 of these so have an assortment of backs. Some better than others.

    Think about what the Toast man says above. I too have noticed my advancing action can effect the spacing.
    If you get too rough it can become sketchy.

    I have a Rapid that cant switch backs midroll so I only need one good back.
    These beasts ARE beastly but a little known gem and well worth getting the funk out of them and using them even if
    they do have an eccentricity or three .
