Legacy lens test.....

    OK, at the risk of more ridicule from Tony, I got my OM-4/3 adapter this
    morning. I took a set of test shots using all my old OM lenses, and also
    compared the new E lenses.

    There are the following lenses used. Each shot was taken at the extreme
    of zoom on the zoom lenses. The fixed lenses were one stop off wide
    open.

    E-System 14-45
    E-System 40-150
    OM Zuiko F1.4 50mm at F2
    Hanimex 28mm at F5.6
    Zeiss 70-210mm at max aparture
    Vivitar 75-250mm at max aparture.

    I'll leave you to see if you can tell which is which.

    These are taken in RAW format, and simply exported to JPGs on a web page
    using iPhoto with no adjustments made at all. I've limited the sizes for
    practical reasons.

  2. I reckon P9270284.ORF was taken with the Zeiss.
    P9270281.ORF - Hanimex 28mm?
    P9270257.ORF - one of the E-System lenses?

  3. Strange. Does the adapter modify the focal length of the OM lenses at all?

    The focal length on the legacy lenses is doubled, but the adapter
    doesn't have any effect otherwise.

  5. I think:

    E-System 14-45 @ 14 P9270281
    Hanimex 28mm @ 28 P9270282
    E-System 40-150 @ 40 P9270283
    E-System 14-45 @ 45 P9270277
    Zeiss 70-210mm @ 70 P9270273
    Vivitar 75-250mm @ 75 P9270275
    E-System 40-150 @ 150 P9270270
    Zeiss 70-210mm @ 210 P9270268
    Vivitar 75-250mm @ 250 P9270263


    However I can't work out which I think was taken with the OM Zuiko F1.4 50mm lens.

    P9270284 and P9270257 both look to have been taken using one of the E-System
    lenses.

    What's my score?

    Wrong. That was the E-system at 45
    Wrong. That was the 50mm Zuiko.
    Spot on.
    And Spot on again.
    Nope, that was the Zeiss at 210mm
    Nope, That was the Vivitar at 250mm
    Close, it was that, but with a Vivitar 2x converter as well :)
    That was P9270277.
    Ooh, 284 was the E-system at 150mm, but 257 was the Vivitar at 250mm
    (and hand held as well). I got better lighting for that shot.
    I reckon 4.5 :)

    I know these aren't the best of shots, they were done in a bit of a
    production line, so I didn't pay much attention to exposure etc. The
    test was just to check definition and focus.

    I set the camera on a tripod with a 1sec mirror lock, and a 2 sec timer
    for each shot.

    I think they do show that a legacy lens can be alright though, albeit
    with a little practice needed at focussing :)

    Complete nonsense. The focal length is **unchanged**.

    More factual errors!

    [As anyone with a little more knowledge than Andy will be aware, a
    digital sensor that is smaller than 35mm film means that the angle of
    view of the lens is commensurately reduced. This gives the same
    appearance as a longer focal length lens used on 35mm film. In the
    case of Four Thirds, the effect is comparable to using a lens of
    double the focal length on 35mm film.]

  9. And about time too! I wondered how long that was going to take.

    Now who's getting personal?

    Once again, you are posting misleading "information" that is just
    plain *wrong*. Other people will read the nonsense you post here and
    some of them will believe enough of it to make the wrong decisions
    about buying or using equipment.

    I don't like to see others misled because you will not make the effort
    needed to get your facts right before posting them on a public forum.

    There is more than one way to express your own opinion.

    It does take a lot with me, but that does feel better :).

    When the facts are totally wrong, as in your case, it is better not to
    express them at all.

    Yes, and Tony Polson's way strikes me as decidedly more civilised!

    Huh?

    OK, the last bit wasn't as civilised, but obviously you haven't followed
    the rest of his persecution of me, I'm afraid I just finally snapped.

  17. May I refer the honourable gentle(wo)man to the rest of this thread, 'Legacy
    lens test...', and the whole of thread 'First pics with the E500'.
