In 1996 Tokina created a new class of telephoto lens when it introduced the original AT-X 840 AF. This was the smallest zoom lens available that had a bright f/5.6 aperture at 400mm. Now Tokina has recreated 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 low-profile 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.
Another feature that makes the AT-X 840 AF D an excellent traveling companion is the zoom lock switch. The zoom can be locked at 80mm to so there is not chance of “zoom creep” when the camera and lens are being carried over the shoulder.

Tokina kept ease of use in mind with the new AT-X 840 AF D, the new BH-725 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.

When used on digital SLR cameras the AT-X M35 PRO DX lens gives the same angle of view as a 52mm lens. The close focusing distance of the M35 is an amazingly close 5.5 in. (14cm) yielding a macro ratio of 1:1 or life-sized reproduction with excellent sharpness. Its compact size makes it easy to carry almost everywhere and the wide f/2.8 aperture allows for easier viewing in low light situations.

The front element of the AT-X M35 PRO DX has a newly formulated WR or “Water Repellent” optical coating on the glass. This new coating makes marks such as spots left by water or finger-prints much easier to clean than standard multi-coating.**

Tokina’s exclusive One-touch Focus Clutch Mechanism allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the camera to focus manually. There is no need to change the AF-MF switch on Nikon cameras*** and there is no second AF/MF switch on the lens for Canon, everything is accomplished by the focus ring.

The new Tokina AT-X 165 PRO DX makes an excellent standard lens giving the digital photographer the equivalent of a 24-75mm lens in terms of film. From the nature enthusiast to the portrait artist to photojournalist, everyone will be able to appreciate the AT-X 165’s bright F/2.8 constant aperture. This wide aperture allows for faster shutter speeds in low-light conditions or a more shallow depth of field for more pleasing portraits. The out of focus background from a wide aperture setting concentrates attention on the subject giving the photo more strength and intimacy.

The rear optical group of the lens contains 1 SD (Super-Low Dispersion) glass element to reduce the number of elements (pieces of glass) in the optical design in order to make the lens more compact, light-weight and faster focusing.
