Description:
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.

Pros: compact, very sharp images, fast AF, tank like build quality, solid tripod collar
Cons: plastic friction knob on tripod collar, no image stabilization

I purchased this lens new after much deliberation between this and a Canon 70-300 IS, the price of both being about the same. I'm a semi-pro and shoot primarily sports, but bought this more as a travel lens. What a pleasant surprise when I started shooting. The IQ is better than the mid-range Canon 70-300 IS with strong colors and good saturation and the shots wide open handheld at 400mm were impressive. It compares very favorably with my Canon 100-400L in IQ and AF speed but is not as sharp nor as fast AF as my Sigma 120-300, 2.8. Looking at the images in my computer with no PP, I was counting the individual hairs on my golden retrievers's tail and the stitches on an American flag at full zoom, hand held and wide open.

I love this compact lens that's so easy to carry when traveling and produces such sharp images. I use a compact monopod to stabilize it at 400mm unless I am shooting with lots of light and can boost the shutter speed. It would be nice to have IS, but then it would price itself into my Canon 1-4L range. The included lens hood with an integrated wheel for turning a polarizing filter probably speaks to Tokina's intent to market this as a compact travel lens for which it is ideally suited.

At just over $500, this lens is probably the best value on the market that encompasses the 80-400mm focal lengths. This is a metal lens with Tokina build quality and smooth as silk zoom feel.
