Olympus has announced the M.Zuiko Digital ED 300mm f/4 IS PRO lens for Micro Four Thirds mounts. It provides an equivalent 600mm field of view. It has optical image stabilization that provides up to 4-stops of shake reduction. It also offers 5-Axis Sync Image Stabilization that works in conjunction with the sensor-based image stabilization on certain Olympus cameras.
The lens features three HR elements and one E-HR element for a compact size while correcting for curvature and spherical aberrations. Additionally it has three Super ED Elements and Z Coating Nano to minimize flare, ghosting and reflections. It has a close focus distance of 4.6′.
The lens is also compatible with the Olympus MC-14 1.4x Teleconverter, which provides an 840mm equivalent reach.
The Olympus M.Zuiko Digital ED 300mm f/4 IS PRO lens retails for $2499. It’s available here at B&H Photo.
It doesn’t provide the equivalent “reach” of 600mm (or 840mm with teleconverter), only the same crop. So the 300mm only gives you the same reach as a 300mm on full frame, but with the same crop/frame/composition as a 600mm full frame equivalent. The full frame 600 is giving you much more reach/telescopic ability. People keep making this mistake!
