A complete range of lenses in one! This is the world's first 80-400mm f4.5-5.6 that can boast a brightness of f5.6 even at the 400mm setting. This lens has been minimized in size and weight and can easily be used at the 400mm end with today's faster emulsions. The optics have a built-in flare cutter mechanism which remove unnecessary light (flare) and gives clean, sharp images. Adding a dedicated bayonet lens hood, designed for maximum coverage, further eliminates flare.
