Equivalent to 70-200mm on full-frame cameras, the Olympus Zuiko Digital ED 35-100mm f/2 Lens for Four Thirds cameras is an extremely versatile and useful telephoto zoom that is great for sports, action, and portraiture. Offering a fixed f/2 aperture, users can work more effectively in low light and create images with a shallow depth-of-field. Further benefitting image quality is the use of one Super ED and four ED elements, which help combat aberrations and maximize contrast. The fast AF system can be adjusted through the use of a focus range limiter while a detachable tripod foot helps when working on a tripod or monopod. Additionally, it has a 9-blade circular diaphragm for smooth bokeh and features a splash and dustproof construction. It is compatible with Micro Four Thirds cameras through the use of an optional adapter.
