Panasonic LUMIX S 100-500mm F5-7.1 O.I.S.

Panasonic's first lens to reach 500mm, and the long telephoto the LUMIX S range had been missing for wildlife, motorsport and distant landscapes. It weighs 1,285g without the tripod foot and is 196.1mm long at 100mm, and it works with Panasonic's 1.4x and 2x teleconverters for up to 1000mm at f/10 and f/14.

The 19-element design uses two UED, two ED and two UHR elements, and the 11-blade aperture keeps highlights round. A Dual Phase Linear Motor drives the focus, the in-lens O.I.S. combines with body stabilisation for up to 7 stops (Dual I.S. 2), and close focus of 1.5m at 500mm gives 0.36x for insects and flowers. The barrel has a zoom-torque ring, focus limiter, O.I.S. mode switch, zoom-limit switch and an assignable focus button. It is dust, splash and freeze resistant (-10°C), with a fluorine-coated front element.
