The Olympus M.ZUIKO Digital ED 300mm f/4.0 IS Pro is the world’s most compact, versatile and stable 300mm telephoto lens (as of Dec 2015).

This Olympus 300mm Micro Four Thirds fit Lens also has the world’s most powerful 6-step image stabilisation system (in combination with matching Olympus camera models) and boasts the shortest focusing distance for telemacro photography in the category - just 1.4m from subject to camera.

Stabilisation ensures image quality

On the top of the lens barrel there are three switches that can likewise be operated without glancing up from the viewfinder, using just one finger. On the left, the L-Fn switch can be customised to trigger one of 27 assignable functions. Next along is the On/Off switch for the in-lens IS, for use with a tripod or stable perch. The other switch toggles the focussing area. The short-shot potential of this lens is likewise exceptional, offering magnification of 0.48x with as little as 1.4 metres between the subject and the camera.
