    Thanks for the review David. How did you find the power zoom compared to manual?

    Its not something I'm used to. I've had to force myself to use it. It seems very smooth however. As I wrote in the review the zoom ring itself is very light and seems to "float". I'm going to give both methods a go with some video and see how smoothly they work.

    i do enjoy your reviews David ... even when it's about a lens or camera I will never own or want to own (like this one) ... neither "fanboy" or cynic, just personal opinion and experience clearly expressed and explained ... thanks

    Yes - I'm in touch with the original poster and have just sent him the details of the test shots I did.

    I've just come back from trying it out again and I seem to have a problem around the 1/100 to 1/250 sec. mark. Below that and above 1/320 sec. the OIS seems to work fine.

    I'm off to check it again, to see if this was me or its a repeatable issue.

    There does seem to be a problem with the lens I have at around 1/100th. sec with the OIS on.

    Thanks.

    I just wanted the folks who have this lens to come together and maybe make a determination about the lens and its OIS. I know that some folks are having IBIS issues with the E-PL3 and E-PM1 at certain shutter speeds as well.

    With my old panasonic FZ3 which had OIS, I rant into an issue where it would work at 2 and 3 stops below the safe shutter speed. Get to 4 stops and it was blurry. Get to 5 stops and it actually produced a sharp image. I've had some theories on this, but sometimes there is other evidence to refute my theories. Oh well. It looks like a fun lens to use.

    I agree. I'm getting very sharp results with the 45-175mm lens on a G3 at 175mm and 1/15th. sec. but from 1/30th. > 1/160th. sec. its not sharp. ???? Then from 1/250th. sec. it sharpens up again. Trying the same lens on an Olympus E-P3, using the IBIS it works fine, from 1/15th sec. upwards.

    Why? I haven't a clue.

    What about with the EP3, but with IBIS off, and OIS on? And with OIS off on the G3?

    Perhaps there's a bad OIS algorithm?

    Armanius,

    No way to turn on the OIS from a PEN since there is not physical switch, at least that's what I've read.
