About six months after teasing a Micro Four Thirds concept camera at PMA 2009, Olympus released the PEN E-P1. The E-P1, modeled after the PENs from the film days, was the company's first venture into mirrorless and only the third MFT camera on the market. The E-P1 featured a 12.3MP Live MOS sensor, in-body image stabilization, TruePic V processor (they're now on VIII), a fixed 3" LCD and 720p video capture. It didn't have an electronic viewfinder, but Olympus did sell an optical one designed for its 17mm pancake lens.

The E-P1 was pretty good for a first outing, especially in terms of design and image quality. It did lose points for its AF system, lack of a flash or viewfinder and confusing menu system (some things never change), however. Even so, the PEN E-P1 earned the coveted 'Highly Recommended' award from our editors.
