The M.Zuiko Digital ED 40-150mm f/4-5.6 R from Olympus is an 80-300mm equivalent telephoto zoom for Micro Four Thirds mirrorless cameras. Its modest maximum aperture helps to realize a compact and lightweight form factor while an advanced optical design, which uses extra-low dispersion and high refractive index glass, controls a variety of aberrations for notable sharpness, clarity, and color accuracy. Extending its versatility, this lens also features a Movie & Stills Compatible autofocus system, which is quick, quiet, and precise to suit both photo and video shooting applications.
