    I'm looking at a friend's old Olympus OM-1 with several lenses. I wonder
    if the lenses can be used on the new Oly digital? The camera still works
    but hasn't been used in ages. Seems like a nice kit, not super fast
    lenses but supposed to be quite nice quality. Beautiful compact metal
    manual body classic SLR with prism focusing aid & light meter.

    Almost all OM lenses can be used on the Four Thirds cameras (Olympus,
    Panasonic and Leica) using an adapter. Some work well, some work well
    but with limitations, and some work less than well.

    That is because OM lenses were (obviously) not designed with digital
    sensors in mind, unlike the Zuiko Digital lenses which are
    specifically designed for digital with near-telecentric optics.

    If you go to the Olympus web site for your country, you will find a
    table showing which lenses work best, and with what limitations. There
    is surprisingly good agreement between its recommendations and what
    Olympus users have found in practice, so it should help you to decide
    whether the lenses are worth buying:

    http://www.olympus.co.uk/consumer/dslr_OM_Adapter_Compatibilities.htm

    Don't forget that the small Four Thirds sensor means that the
    effective field of view is that of a lens of double the focal length
    on 35mm film. The 21mm thus becomes an equivalent 42mm; the 28mm an
    equivalent 56mm, and the 50mm an equivalent 100mm. The apertures do
    not change. A 50mm f/1.4 becomes an equivalent 100mm f/1.4, but note
    that Olympus recommends using apertures only between f/2.8 and f/8.

    All three fixed focal length lenses are excellent performers on 35mm
    film. I have little knowledge of the 35-70mm zoom, but the aperture
    range recommended by Olympus suggests that it will not perform
    especially well on a digital SLR.

    Hmm so wider apertures vignette badly on digital? Thanks for the info,
    looks like it's best use is as a manual film camera.

    I looked at prices for sold items on ebay & posted to the page above. I
    don't know if she even wants to sell, it was used (carefully) many years
    ago. I was just curious, it's a shame to have such a nice kit sitting in
    a box.

    looks like the body sells for $50
    35-70mm lens $50
    21mm lens $360 for the version with better coating
    28mm lens $50
    50mm lens $50
    135mm lens $40

    Seems like great prices except for the 21mm.... ouch. That seems a bit
    steep.
    *Maybe* if it was a 2.8 in new condition.

    Cheers,

    You will get some vignetting, but I think a more serious problem would
    be colour fringing.
    You're welcome. It is well worth looking at the Olympus DSLR forum on
    dpreview. The issues that arise when using OM lenses on Four Thirds
    DSLRs has often been discussed.

    The longer lenses work best, the wider ones not as well. In fact, an
    ordinary digital kit lens works as well at wide mode 14mm than would an
    old 35mm lens. But Olympus has nothing like the 50mm f1.4 now and it
    allows for a fast lens on a digital. The only other alternative is a
    Sigma digital 30mm f1.4 which costs about $400.00. I've compared
    longer lenses and the 35mm lenses do have another attribute, they do
    not vignette much if at all.

  10. Well also bear in mind the 2x crop factor, so your 50mm lens will give you the
    same field of view as a 100mm lens on a 4/3rds camera. So for wide angles
    wider than 28mm, use the digital lenses (7-14mm, 11-22mm, 8mm fisheye). For
    28mm, the usual kit lens will give you that, but the medium level 14-54mm is
    generally thought to be a better lens.

  11. You'd be hardpressed to get a 1.4 50mm at $50 but you could do so
    easily for 10 or 15 more. With the lenes you have, why don' t you look
    for a newer body, such as the motorized OM2 or even the OM10. They are
    cheap on ebay and you'd have a fabulous manual film camera.
