Re: Stabilisation comparison test

OK weird results. I did this 3 times just to make sure and it did it every time.

Panasonic G3, 45-175mm lens, OIS (Type 1) Hand held.

I used a spagetti jar as you can see, and photographed at 6 paces away. At 1/15th. sec. and 175mm. it was sharp. 1/30th. 1/60th. and 1/125th. were not sharp. 1/250th. sec and 1/500th were sharp again. As I said I repeated this 3 times, and it was the same every time.

This fits in with what I was getting when I went out earlier for a "real world" test. Images around 1/60th to 1/160th sec. weren't sharp with the OIS on, but shots below and above this were.

Didn't someone else get the same type of results on your thread?

Thanks for the info, appreciate your help.

I was able to replicate your 1/15 shots and get very sharp shots of a coke can at ISO 160, F8/10, 1/15 but only at about 3/5ft @ 175mm, 350 EFL. any further away and the double edges return.

Could i ask you to try a test at more realistic distances, maybe you could replicate my test, a subject of no more than 5 inches across @ about 20ft, a range of shutter speeds from 1/15 to 1/500, you only need to take one image at each shutter speed.

It would be very much appreciated and would eliminate your lens one way or the other.

Since I kept the shutter speed constant, aperture was around f8 - f13. It varied from shot to shot. Shutter speed was 1/15th. sec. for all shots. ISO was 160 for the G3, 200 for the E-P3. Distance varied between 5' and 15'.

Hi, could you please give me the EXIF data on your G3 and 45-175 test shots please.

Could i have the aperture/shutter speed/ISO/ and distance to subject please.

I want to try and replicate your findings.

I did read your original post, which gave me cause for concern, and I tried to replicate the problems that you were having but couldn't.

I understand your problem, and know just how annoying and frustrating it can be. I've had lenses where the stabilisation was a problem. As I mentioned in an earlier post I had a Nikon VR lens which produced the most peculiar result of eliminating camera shake from most of the image but not all of it!! I informed my dealer and the lens was replaced, eliminating the problem.

Hope you sort it soon.

Looking at your test my copy of the 45-175 must be a lemon, or part of a box of lemons considering i'm not alone, thanks for this test, it gives me hope that i will end up with a 45-175 that works right.

I've added another part to the review where I've compared the Mega OIS of the lens on a G3 with the in-body IS of the E-P3.

Firstly this seems to confirm that there is no OIS when I use the lens on the Olympus.

Secondly, both systems seem to work really well.
