IBIS bug on E-PM1 demonstration
Dec 11, 2011

The top row, IS was off.
Bottom row, IS 1.

Both rows, f/2.0 (with the 25mm lens), 1/100 sec, ISO 320.

I took many more photos that this, the bottom row is not a fluke but representative samples of how my E-PM1 was working TODAY.

What I noticed is that when I put the shutter speed to 1/20 instead of 1/100, sharpness actually IMPROVED with the IS turned on. So I think this is, as some people have hypothesized, related to the IS mechanism being shake by the shutter slap, and this subsides on longer exposures.
