Another first from Tokina, a complete range of lenses in one! Tokina created the worlds first 80-400 mm f/4.5-5.6 lens that can boast a brightness of f/5.6 even at 400 mm! Its still the worlds smallest 80-400 mm zoom lens.
The AT-X 840 AF-II model adds a built-in tripod collar and refinements in the auto focus gearing for a smoother AF. The optical design incorporates SD (APO) glass and an internal flare cutting mechanism, which removes unnecessary light (flare) to render clean sharp images. Another highly functional feature of the AT-X 840 AF-II is the zoom lock, which secures the zoom lens in its most compact position at 80 mm.
Using the included bayonet lens hood (Tokina always recommends using a lens hood) further eliminates unwanted flare. All metal barrel construction, chrome plated brass mount plate and SD glass all combine to create an AT-X lens built for travel photography.
