A wide-angle pancake lens with a fixed focal length (the 35mm equivalent of 34mm), this Olympus M.Zuiko Digital 17mm f/2.8 lens is well suited for everything from landscapes to portraits to close-up photography. The digital-dedicated design produces razor-sharp images, while its slim profile makes the lens easy to slip into a pocket or carry mounted to your camera. It sports a five-blade circular aperture for nicely defocused backgrounds, along with a unique 37mm filter thread that allows you to use a range of different filters and even attach a lens hood when you need to block stray light.
