The Olympus OM-D E-M1 has just been announced, stepping into the O-MD line as both the flagship Micro Four Thirds camera and successor to the E-5 DSLR. Olympus is billing the E-M1 as the E-5's successor because it's the first m4/3 camera to offer decent autofocus with legacy Four Thirds lenses.

The reason for the improved Four Thirds autofocus performance is the E-M1's 16.3-megapixel Live MOS sensor, which has on-chip phase detection. This promises that the E-M1 will focus legacy Four Thirds lenses (using the optional MMF-3 adapter) at much faster speeds than previous Olympus m4/3 cameras.

We've been shooting with a production E-M1 for some time, and have prepared some first impressions, including a samples gallery and studio test shots. Follow the link below to learn more about Olympus's latest flagship.
