Olympus 14-150mm (M43rds) gets the SLRGear review
Curiosity killed the Micro Four Thirds cat? We can't answer that, but if you head on over to SLRGear.com, you can find a brand new review of the Olympus 14-150mm Micro Four Thirds lens. This is an unstabilized superzoom lens since Olympus E-Pens include sensor-shift stabilization. This will make it a different trade-off for Panasonic M43rds camera owners since those cameras don't offer sensor-shift because their lenses are stabilized. The E-P1 was used as the "base" camera for the test.
The lens is currently available for pre-order at Amazon for $600. It is in the "temporarily out of stock" status, which is a sign that it may start shipping or it has began shipping and sold out. Or it is somewhere in-between.
