Expert Advice The 135mm f/2.8 is widely considered the classic "portrait" telephoto lens. Its focal length provides excellent subject isolation and a beautiful compression effect that flatters facial features. On an Olympus OM film camera, it balances perfectly due to its lightweight design. For digital mirrorless users (Sony E-mount, Fujifilm X, or Micro Four Thirds), this lens is a fantastic choice for a compact telephoto setup via a simple adapter. We recommend shooting at f/4 or f/5.6 for maximum center-to-edge sharpness, though f/2.8 provides a gorgeous, soft bokeh that is perfect for artistic headshots.
