A long-reaching super telephoto for Micro Four Thirds mirrorless cameras, the M.Zuiko Digital ED 300mm f/4 IS PRO from OM SYSTEM 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.
