lens adapters

Discussion in 'Darkroom Developing and Printing' started by Rex the Strange, Oct 14, 2005.

  1. Got a question - I've recently bought a camera that supposedly came
    with lenses. The camera takes the infamous x-fujinon lenses (which is
    why I bought it - I have some of those and another x-fujinon camera -
    the one I started with). The lenses, however, aren't x-fujinon and,
    after some research I have found that they have Pentax P/K bayonet

    I already have a camera body that takes M42 mounts lenses, so now I
    have three different lens types. So, I'm wondering if it's possible to
    connect any of these lenses to by M42 body, either the M42s or this P/K
    Bayonet. Does anyone know of an adapter that will do the job or, better
    still, a shop that stocks every body/lens adapter in existence?

    I don't think rec.photo.darkroom is the best place for this question. You
    might want to post to rec.photo.equipment.35mm (if it's active; I just see
    the name in my list at the moment).

    That said, the short answer is that most lens-to-body adapters will
    degrade the image quality, either because they won't permit infinity focus
    or because they'll include optical elements to compensate. Your best bets
    are to return the camera/lens package to the seller for a refund or to
    sell the K-mount lenses separately (on eBay or to a local dealer). You can
    then use the funds to buy new X-Fujinon, M42, or Tamron Adaptall lenses.
    (The Adaptalls are designed to use adapters to mount to a wide variety of
    bodies, so they're very handy if you have cameras with multiple mount

    As to adapter sources, B&H (http://www.bhphotovideo.com) has a wide
    selection of adapters, including one (with optics) to mount K-mount lenses
    on M42 bodies (but it's back-ordered). I know there's at least one place
    on the Web with an even wider selection, but I lost the bookmark a few
    weeks ago. :-(

    No. You can not go from a bayonet to a screw thread body as the adapter
    to do so will add thickness and you could only use it to do macro and
    close up work.

    You can adapt Pentax screw mount lenses to Pentak K mount with full
    automation and no loss of infinity focus. Novoflex probably has the most
    adapters to convert lens/camera combinations. Check their web site

    Wrong. Absolutely wrong. Couldn't be more wrong.

    You can get adapters to go from and to all sorts of mounts. As Rod
    points out these adapters compensate for any differential in focal
    depth by providing corrective lenses.

    Thanks Rod - I did find one on B&H (I go there frequently - best photo
    store in the continental US). As for the wrong forum, I did try to post
    on rec.photo.35mm which would have been ideal except that it's archival
    only. I will look at rec.photo.equipment.35mm - thanks for the
