Thanks for the review David. How did you find the power zoom compared to manual?
There seems to be several owners of this lens on dpreview that are having trouble with the new Power OIS.
This thread here is the one I am refering too:
45-175 power OIS, not impressed at all. [Page 1]: Micro Four Thirds Talk Forum: Digital Photography Review
Even panasonic has acknowledged the problem, at least according to one user. Any issues?
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.
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.
Long long time ago I had a Panasonic 45-175mm with my GH2 and I couldn't get sharp pictures at shutter speeds in a wide range around 1/125 s IIRC. I blamed it on shutter shock of the GH2 which did not have an electronic first curtain. So just an idea: try electronic first curtain (if available and not already engaged). My transition to a Sony NEX-6 with electronic first curtain made a huge difference and much later I went for the Sony A7 instead of the A7R because of the electronic first curtain of the former. And yes, also the A7R has problems with longer focal lengths, i.e. shutter shock.I agree.

Is your GX8 up to date on firmware? One of the GX8 updates does an override on the manual shutter at potential combinations for SS as I recall.Don't usually revive old threads but I just scored a great deal on one of these and must say it works Great on my GX8! Read all the horror stories about "shutter shock", and OIS / IBIS causing loss of sharpness at certain shutter speeds, yadda, yadda, yadda. Well, tried everything I could to make anything bad happen and got nothing but stellar images!....
I don't have the camera so I can't confirm one way or another. But I was under the impression the FW would override the setting of manual shutter for those combinations.Yes, it's on V2.2, but even when I was using the mechanical shutter I couldn't get the combo to misbehave.
