OM System M.Zuiko 100-400mm f/5-6.3 IS II

The second-generation 200–800mm-equivalent zoom adds Sync IS (up to 7 stops with an OM-1 or OM-3), a fluorine-coated front element and IPX1 sealing to the most practical wildlife lens in the Micro Four Thirds system. At 1.1 kg with a removable tripod collar and 0.57× equivalent close focus, it doubles as a tele-macro for insects and birds alike, and takes the MC-14 and MC-20 teleconverters.
