A complete range of lenses in one! This is the world's first 80-400mm f/4.5-5.6 that can boast a brightness of f/5.6 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.
