Along with the E-M1X, Olympus today also announced a new super telephoto zoom lens in developing: Olympus M.Zuiko Digital ED 150-400mm f/4.5 TC 1.25x IS PRO Lens.
This hefty lens will have a standard focal range of 300-800mm equiv. on Micro Four Thirds bodies, with a built-in 1.25X teleconverter increasing those numbers to 375-1000mm equiv., at the cost of 2/3-stop of light. If you want even more reach, the lens will also be compatible with Olympus’ new MC-20 2X teleconverter.
The lens will be stabilized and will work with the 5-axis IS systems built into modern Olympus cameras for extra shake reduction. As one would expect, it will be fully weather-sealed and Olympus claims it should function at temperatures as low as -10°C/+14°F.
The 150-400mm F4.5 TC1.25x IS Pro will be available in 2020, and pricing has not yet been disclosed.
