OM-D E-M5 a huge disappointment for me...

In my testing, I have found some signs of different behavior even at the same FL. The most clear-cut example is the 45/1.8 versus the 14-45 at the long end and the 40-150 at the short end. I have no trouble with the 45/1.8 (although some other people have reported issues with this lens as well) but both the 14-45 and the 40-150 are affected when used at the same FL as the 45. On the 14-45, I can get rid of most/all of the problem by using OIS rather than IBIS (the OIS on this particular lens, not others, appears to be able to counteract the shock, whereas IBIS can't) but with the 40-150 no such solution is available.
