    HI Folks

    I have a NIkon d80 SLR and my husband has a bunch of old lenses he used to
    use for his olympus ompc. But these are generic lenses so he had to use a
    lens mount adapter. This adapter does not fit on the D80, but is there a
    lens mount adapter that I can use for the D80 so I can use these nice
    lenses?

    THey are Rokunar MC auto zoom 1:5.6 75-300mm - no k8610109

    the other is Seimar 1:6.3 , f=400m, 820788


    I also have this SAKAR olympus flash, it is 77D-0. IS this compatible with
    some kind of adapter?

    Thanks sooo much

    If there is, it won't be cheap.

    when you say 'generic lenses' - do you mean a t-mount? or something
    like the tamron adaptall? either way, finding a nikon adapter
    (particularly a t-mount) won't be a huge problem, and the lenses should
    work fine, but with no metering at all (and no autofocus, obviously).

    on the other hand, if they are dedicated olympus mount lenses, it will
    probably not work at all. the registration distance for olympus is
    slighly longer than for nikon, so even if you found an adapter, it
    wouldn't focus to infinity unless it had an additional lens element in
    it, and that would compromise the image quality. it is also possible
    that the olympus lens mount has protruding mechanical parts that would
    preclude it from mounting.

    and in my brief google search, i found:

    0700

    is that you?
    some older flashes had high trigger voltages and can fry modern
    cameras. i don't see a listing for that flash, so either you need to
    measure the voltage, or just play it safe with a wein safesync adapter.
    that adapter also takes care of the second issue of the extra pins on
    the hotshoe of the flash possibly conflicting with the ones on the
    camera.

    the other issue is that the flash will only work in manual mode (where
    you set the f/stop based on distance) or automatic mode (where the
    flash itself measures the light). the camera's ttl flash system will
    not work, and you will probably also need to manually disable ttl flash
    in the menus.

    nikon's i-ttl flash system is excellent, and even the low end nikon
    sb-400 will be significantly more flexible than messing around with the
    sakar. keep in mind that the nikon sb-400 flash isn't that much more
    money than the wein safesync adapter...

    Don't do it.
    You can buy new latest Nikon 70-300mm lenses that Autofocus & Autoexposure
    with your
    D80 for about $100.

    Even if you could adapt those old lenses you would have to focus manually
    and
    you would have to use trial and error for proper exposure.

    Thanks folks for your great input. It sounds like more trouble than it is
    worth so I will ebay those nice old lenses along with the camera soon.
    But thanks also for the tip on the lens!!
