OM System M.Zuiko Digital ED 150-600mm F5.0-6.3 IS

This is the long end of the M.Zuiko line: 150-600mm on Micro Four Thirds, which reads as 300-1200mm in 35mm terms. That is the reach birders and wildlife shooters normally pay a supertelephoto prime for, in one hand-holdable zoom with 25 elements in 15 groups behind a 95mm filter thread. Minimum focus is 0.56 m across the range, close enough that the same lens covers a dragonfly as well as a distant raptor.

It syncs with the body's 5-axis stabilisation for up to 7.0 stops of compensation, which is what makes 1200mm equivalent usable off a shoulder rather than only off a gimbal head. The barrel is dust-sealed and weather-sealed to IPX1, so it stays out in the weather that produces the pictures. The MC-14 and MC-20 teleconverters take it further, to 1200mm native and 2400mm equivalent. The aperture is a 9-blade circular design, running f/5.0 wide to f/6.3 at the long end.
