This FE 100-400mm f/4.5-5.6 GM OSS Lens from Sony will satisfy many photographers and videographers who are looking for a bit of extra reach with their full-frame E-mount camera. It also features a relatively compact size through the use of an f/4.5-5.6 maximum aperture range, and it is equipped with both a Direct Drive SSM autofocus system and Optical SteadyShot image stabilization for outstanding performance at all focal lengths.
