NEW TOKINA AT-X 840 AF D lens
LONG BEACH, CA. (March 29, 2006) -- THK Photo Products, Inc., announces the Tokina AT-X 840 AF D 80-400mm f/4.5-5.6 lens for Digital and film SLR cameras.
In 1996 Tokina created a new class of telephoto lens when it introduced the original AT-X 840 AF. This was the smallest lens available that had a bright f/5.6 aperture at 400mm. Now Tokina is recreating the lens for the digital age.
Still the smallest SLR lens available that zooms to 400mm, the AT-X 840 AF D has a smooth and quick internal focusing system that means the all-metal inner barrel that houses the heaviest glass elements does not have to rotate when the lens focuses, making it much faster than the previous models.
Optically, the AT-X840 AF D has new multi-coatings applied to the elements that are formulated to compensate of the highly reflective CCD and CMOS sensors in today’s Digital SLR cameras. The new multi-coating greatly reduces the chance of internal flare or ghost reflections.
A built-in tripod collar makes for a well-balanced camera/lens combination when using a tripod or monopod. For best results, Tokina always recommends using a tripod or monopod with telephoto lenses.
Tokina kept ease of use in mind with the new AT-X 840 AF D. A new lens hood with the a PL Assist spring loaded thumb wheel allows a circular polarizer or special effects filter to be rotated while the lens hood is in place. No more removing the hood to change the position of the filter.
