The new Olympus f2.8 lens that came out together with the new Olympus E-M1 camera has received a brand new high profile review, it is waiting for you to read at Imaging Resource's SLR Gear.
As of the time of writing, the lens remains in pre-order at $1000, but some sellers are offering it for $1100 or even $1200. For the latest updates, stay tuned to the E-M1 and 12-40/2.8 Stock Status page.
Prime time of the micro four thirds kind now at Focus Numerique (computer transalted) where they take a look at the Olympus 17mm f1.8 prime lens. Not to be confused with the older 17mm f2.8 pancake lens. This is not a pancake.
Zoom zoom at ePhotozine with a new review of the Olympus M.Zuiko Digital ED 14-150mm f4-5.6 M43rds lens. Superzoom but unstabilized (Olympus favor sensor-shift stabilization but Panasonic camera body users don't have this feature).
