The Olympus Zuiko Digital 14-54mm f/2.8-3.5 II Zoom Lens is part of the High Grade Series, and this II version has been upgraded with several improvements. The lens is a portable, high-quality Digital Zuiko wide-angle zoom that provides edge-to-edge sharpness and superb color reproduction.
This II version uses a 7-bladed circular aperture mechanism, which produces more attractive background defocus points. It also integrates with the "High-speed imager AF" system included in recent Four Thirds DSLRs.
The fast f2.8/3.5 aperture makes it ideal for low-light situations while rendering a bright viewfinder image in the camera for easy focus and composition.
