Product Details
Tokina created the first 80-400mm AF Lens in 1996 when it did, it created a whole new class of telephoto lenses. The latest lens the AT-X 840D is still the smallest lens to zoom to 400mm with a bright f/5.6 aperture. Perfect for travelling, the new AT-X 840D has an internal focusing system which increases AF speed and responsiveness. Further updates make this lens an excellent travelling companion for a Canon or Nikon DIGITAL OR FIM SLR camera. The optics incorporates SD (APO) glass to give clear sharp images and an internal flare cutting design removes unecessary light (flare). To further eliminate unwanted stray light and flare, Tokina always recommends using the included lens hood for best results.
