Olympus has introduced three interchangeable, fixed-aperture, wide zoom lenses designed for use with its E-System digital SLR cameras. The new digital-specific B lenses include the Zuiko Digital ED 14-35mm f/2.0, the Zuiko Digital ED 35-100mm f/2.0 and the Zuiko Digital ED 90-250mm f/2.8.

The 14-35mm f/2.0 (28-70mm equivalent) and the ED 35-100mm f/2.0 (70-200mm equivalent) lenses feature apertures of f/2.0 over the full zoom range, which are intended to maximize the mobility of the zoom range while making the most of the brightness offered at f/2.0. In combination, the two lenses will give photographers the freedom to use the f/2.0 aperture over focal lengths ranging from wide-angle 14mm (28mm equivalent) to telephoto 100mm (200mm equivalent).

The ED 90-250mm f/2.8 has a wide aperture of f/2.8 over its entire telephoto focal length, up to 250mm (500mm equivalent), for photography in more varied lighting situations. The optical zoom range is designed for instantaneous optimal framing in sports and nature photography, where positioning for shots often is subject to constraints.
