When Olympus launched the legendary Pen series of cameras in 1959, this bold and revolutionary achievement rewrote the history of photography. Designed by renowned style guru Yoshihisa Maitani, the Pen represented the perfect marriage of simplicity, style and performance. Five decades later the Olympus passion for innovation is still setting the pace.

With the release of the E-P1, the digital era’s next generation Olympus Pen has arrived: mirrors are no longer a necessary component for digital cameras with interchangeable lenses. The first groundbreaking Olympus Micro Four Thirds model impresses with its incredibly small size, retro style, and ease of use – without giving up any of the benefits of D-SLR quality.
