E-P5 shutter shock ...

I had always wanted a higher spec m4/3 camera. I was extemely pleased with my PM-1 and GF3 other than focusing my 100-300 lens. So when I got my EP-5 and the VF-4, the first thing I tried was focusing with the 100-300 and it worked because of the smaller focusing window. I went downtown and tried my 9-18 and had it set to P to let it do it's own thing exposure wise. That was when I personally discovered SS. At 1/320 and the 9-18 lens it was simple to induce.

One of the concepts at the time was that it was the fault of the IBIS. We now know that it is the first curtain bounce. I compared photos with my GF3 and EP-5 taken at the same settings of the same subject and no SS on the GF3 and SS with the EP-5.

Yes, but that does not demonstrate that IBIS is actually to blame. See for example here:

It just means that your GF3 has less SS than your E-P5, which may be the case for many different reasons.

What this does is destroy the confidence that you have using a camera. In the back of your mind, you are never quite sure. Plus over time I have discovered that it does not focus as well as I would like with the 100-300. Sometimes it surprises me but less often than I would hope.

I certainly do not dispute that there are problems like these. But in my experience, there is no such thing as a camera completely without shortcomings, including unreliabilities of the kind you encounter. My solution in cases like these is to investigate a bit to try to pinpoint when the problem occurs and find a work-around.

The exposure accuracy that it gives me is one area where it is superlative. Having had Canons and a Nikon, their exposures have to be tweaked. Also the high ISO capabilities are superb. But there is the niggling thought in the back of my mind, is it going to be sharp? At 1/320 0r 1/60 or even 1/30 it should be, but will it be?
