The M.Zuiko Digital ED 300mm f/4 IS PRO from Olympus is a 600mm equivalent lens that balances refined optics with a hand-holdable design. Super ED, E-HR, and HR glass elements are combined to control both chromatic and spherical aberrations to provide a high degree of clarity and sharpness, and a Z Coating Nano has been applied to individual elements to suppress lens flare and ghosting for high contrast, color-accurate imaging. A Movie & Still Compatible (MSC) autofocus system is also employed to realize quick and quiet focusing performance, and a manual focus clutch enables seamless switching between focusing methods for more intuitive use. The lens is also fitted with a removable rotating tripod collar for improved balance and support, and the lens is weather-sealed to guard against dust, moisture, and freezing temperatures to benefit working in harsh climates. Three Super ED (extra-low dispersion) elements are used to control color fringing and chromatic aberrations for improved clarity and color accuracy. A Z Coating Nano has been applied to individual elements to significantly reduce lens flare and ghosting to improve contrast and color fidelity when working in strong lighting conditions. Movie & Still Compatible (MSC) autofocus system benefits both photo and video applications due to its smooth, quiet, and fast performance. Dust, splash, and freezeproof construction incorporate 17 separate seals to ensure this lens's performance in inclement conditions and harsh environments. Built-in retractable lens hood shields the front lens element to reduce surface reflections and flare.
