Summary

OM SYSTEM M.ZUIKO DIGITAL ED 150-400mm F4.5 TC1.25x IS PRO is a compact super telephoto zoom for Micro Four Thirds, covering 150-400mm with an internal 1.25x teleconverter equivalent to 300-1000mm in 35mm format.

Its optical design combines the high-speed MSC autofocus with 5-axis Sync IS and IP53 dust/weather sealing, which enables stable capture even at long ranges and helps keep the frame sharp in demanding field use.

In practice, it is built for wildlife and birds-on-action workflows where reach, fast response, and handheld usability matter; the integrated teleconverter also brings useful tele-macro coverage from 1.3m.
