    hi ive just snagged a 35mm macro four thirds lens and ive got the mmf-1 adaptor what i wondered is does using the mmf-1 act as a extension tube as it moves the lens further from the sensor

    if it does has anyone else got this combo as i will need to set the correct length for the ibis i believe ?

    thanks in advance :)

    No it does not. The mmf-1 will set it at its proper distance and make the lens work as intended. I use it on an Epl1 with great results. And the ibis will work automatically just as a native lens.

    The MMF-1 is there to set the Four Thirds lens further away from the Micro Four Thirds Sensor - ie the same distance as the Four Thirds lens would be away from the Sensor in a Four Thirds camera - ie an Olympus E420
    This is because the optics in Four Thirds Lenses are designed to focus onto the Four Thirds Sensor at a greater distance with a mirror in between whereas Micro Four Thirds Lenses are designed to focus directly onto the sensor at a shorter distance because there is no mirror etc in the way which is how Micro Four Thirds bodies manage to be smaller and that much more compact
    The sensor is exactly the same size in both Four Thirds and M43 - it's just the lack of mirror and 'flange to sensor' distance and the resulting reduction in camera size that sets them apart
    Hope this helps your understanding (and that I'm entirely correct in my assertions)
    Regards

    So mini0ne, once you get the lens attached to your OM-D, can you comment on how fast it auto-focuses (if at all)?

    Thanks,

    I had the ZD 35/3.5 macro with DMW-MA1 for a while when I had my EPL1.

    AF is slow. dreadfully slow. It's a pity because the ZD 35/3.5 is one of my favorite lenses.

    I ended up selling the DMW-MA1 and just buying a used E-1 body to use with my ZD 35/3.5 macro. It's a great combo.

    It is painfully slow on the EM5 with MMF3

    Ok, thanks for that input. I am starting to think that any adapted lens is going to be very slow on the EM-5, although it is probably not a problem with just the EM-5. I'm sure it's a byproduct of the adapter.

    If a macro lens is fast in Autofocus it is an exception, not the rule. Macro lenses have a very long focus throw to enable precise focus adjustments and are best used with manual focus... or with a focus rail, or with a gentle sway back or forth of the body.

    I believe the new m.Zuiko macro lens has fast AF... again, that's an exception not the rule. These are nice new improvements in technology which we never saw in the past.

    For non-macro shots, about 2 seconds for the green box to come up with a beep. If the focus distance has not changed much from one shot to the next, then a little faster. Speed on the EM5 and EPL1 is comparable. Focusing in macro mode is slower, but like Ned said, not an issue.

    If the lens is starting from a macro position, it might take as long as six seconds to unwind itself to the proper position for a non-macro shot. Occasionally, it never gets there, if the focus box is small and the target has little contrast.

    It seems just as contrary on the E510. Normal focus is less than 1/2 second, but sometimes it can crawl and sometimes just gives up too.

    I wanted a macro and this refurbed 35mm fit my budget. I'm quite satisfied with it.
