Well this is disturbing (E-M10)

After much hand wringing and gnashing of teeth, I finally pulled the trigger and bought an E-M10, 25mm f1.8 ($100 off) and E-CG1(free), plus another 5% off the total package. A good deal I think. This after 2 months of deliberating, reading reviews, lurking in the forum, etc.

Today, while perusing the Consumer Reports site, I came across their review. One thing stood out and it was "Poor image stabilizer, much lower than most cameras". How can this be? They said every other Olympus camera reviewed had and excellent stabilizer "better than most", even the lowly E-PM2. While I have no plans to return it, I would like to hear from other E-M10 owners and their experiences with image stabilization.

Others' experiences with IS are normally very close to useless, because any system of IS necessarily contains the user within the loop, and every user is somewhat different. The manufacturer can only design for 'the average user' which in all likelihood could be far from yourself or myself.

Since you have camera, have lens, and have additional grip, why not go out and test them yourself in your own typical shooting style/situations? Then you will know how many stops the IS gains you, or not, pretty clearly. Just try the same shots with and without IS at various shutter speeds for enough times to get meaningful statistics. Then you should know how much lower you can set the ISO or how much deeper DoF you can get with the IS. That others report that they can do better or worse than you is completely irrelevant.
