On February 26th 2006, in a packed press conference on the first day of PMA 2006 Panasonic revealed their first digital SLR, the DMC-L1. The DMC-L1 represents another first, it's the first non-Olympus Four Thirds digital SLR which has to be good news for the system which has up until now been an Olympus only affair. When it was announced many noted the resemblance to the E-330, this is no coincidence as the DMC-L1 shares its optical subsystem (lens mount, mirror box, viewfinder, auto focus and exposure sensors) with the Olympus E-330.
