A Pro lens like no other in its class - the M.Zuiko Digital ED 150-400mm F4.5 TC1.25x IS PRO (300?800mm*) sets the standard in super-telephoto performance, portability and precision. Featuring a built-in 1.25x teleconverter, this zoom lens goes up to 500mm (1000mm*) shooting - or add the optional MC-20 Teleconverter for an ultimate 1000mm (2000mm*). 5-axis Sync IS offering up to 8 EV steps of compensation with a compatible camera ensures your photos remain sharp. And because photo assignments can take you anywhere, Olympus-renowned weather sealing is a given. Just like the highly precise and fast autofocus.
