Why? You just need to attach a stabilized A-mount lens (Sigma makes a few of those).[/quote]
You're right. I never knew that. That's very strange. According to B&H there are indeed several OS lenses for Sony. I wonder how it works.

I can think of reasons to choose a PEN over a NEX, but IS shouldn't be one of them. Whatever you gain in IS you loose in ISO, and except for mostly-theoretical situations, clean high-ISO is the more useful option. Preventing blur using clean high-ISO is more beneficial than using a lesser sensor coupled with IS. The reason is that high-ISO also helps freezing subject motion blur, while IS only helps against hand-shake. The only cameras that offer both are from Sony (not the NEX though) and Pentax.[/quote]
The main reasons (for me) are system ones i.e. size and weight (of camera and lens attached) and abundance of AF lenses. IBIS is only the icing on the cake. Yes, APS-C has better high ISO than MFT but IMHO the differences are rather small (about one stop) and are not enough to compensate for the other factors. If anything, it's the built-in high-res EVF of the NEX7 that tempts me much more than the better high ISO.
Last, one must not forget that you sometimes do not want to freeze the action [url="http://www.fredmiranda.com/forum/topic/809532/0#7482263"]but vice versa[/url].
