Olympus Pen E-P1 In-depth Review: Digital Photography Review

From the OM system 35mm SLRs and lenses to the XA series rangefinders and the half-frame Pen models, Olympus has for at least half a century been notable for producing cameras that are smaller than their competitors without sacrificing quality or functionality. And they haven't stopped; the E-450 and its predecessors are still the world's smallest digital SLRs, and the new E-620 is considerably smaller than similarly specified competitors (finally realizing the 'smaller format, smaller camera' promise we were all sold on when Four Thirds originally launched).
