Olympus is on a hot streak for sure. Re the new "entry-level" (hah) OM-D E-M10, DPreview writes:
The E-M10 very much feels more like a third generation OM-D model than a step-down from its two brothers. It borrows many qualities we liked from both of them and presents them in a slightly smaller, lighter package. [...] In fact, the only crucial difference between the two is the E-M10's lack of weather-proofing, and that's not likely to be a significant drawback for a lot of potential owners. It also doesn't hurt the cause that the E-M10 is cheaper at introduction than both OM-D models that came before it.
