The Olympus M.Zuiko Digital ED 150-400mm f/4.5 TC1.25X IS PRO Lens features impressive reach and versatility.

The equivalent focal length can be extended to 1000mm when using the built-in 1.25x teleconverter.
A constant f/4.5 aperture provides a constant illumination throughout the zoom range, the aperture is slightly reduced to f/5.6 in cases where the teleconverter is in use.

Additionally, a series of specialized low dispersion and high refractive index elements help to reduce a variety of aberrations throughout the zoom range in order to achieve high clarity and sharpness.
