The silver M. Zuiko Digital ED 45mm f/1.8 Lens from Olympus has been designed for use with Olympus PEN Micro Four Thirds cameras. With an equivalent focal length in the 35mm format of 90mm, this short telephoto lens is ideal for portraits and for low-light shooting. Its extremely wide f/1.8 maximum aperture can produce beautifully shallow depth of field and is very effective in low-light situations. Its Movie & Still Compatible (MSC) function offers ultra-fast, near-silent autofocus for shooting stills and video. Lens construction using extra-high refractive lenses produces excellent contrast and sharpness in stills and video, with chromatic aberration, ghosting and flare minimized.
