Tokina AT-X 340 AF 100-300mm f/4 SD (IF)

Excellent lens, it's built very tough and machining is nothing short of perfect. The only (minor) downside is the scew on hood and the fact it's pretty heavy (~1.6kg), but screw on hood behaves like an integral part of the lens and it's not like you're...

This is a very sharp lens. I had a chance to use it for the first time today at Jungle Island in Miami. I have no complaints about the sharpness what so ever. It's a great range to bring to a zoo, or outdoor photography. In the low light areas at f4...

I wanted a 300mm lens for my sports photography and this lens came up on ebay and after using it i have found it to be brilliant. My photos are really sharp and i even tested it at a low evening light and the results have been very good.

A gem among gems! This lens is built like a tank and is optically fantastic at all lengths and virtually all apertures (though, I admit, I rarely use it stopped way down). Most of my photos with this lens are portraits at 100-135 f/4 or 300 f/4, and...

I was very excited about this lens at first. The consturction is grade "A". This lens dose lack quite a bit of sharpness. 5x7 prints look great, 8x12 do not. Optics are good, but not great! The lens weight is not to bad, compared to my Sigma 50-500mm....

Sharpest 100-300m lens currently available. Easy to use, tripod collar works great, very well built. Because this was an older lens I was told it might not work 100% with the newer EOS system camera bodies. I had it sent to THK who distributes tokina,...

This large aperture telephoto zoom lens was the first 100-300 lens with a fast, constant aperture of f/4 throughout its entire zoom range. The results I got are briefly summarized below. f/4: Good sharpness, slightly decreasing with the focal length....

I use this lens for photographing figure skating competitions. Since flash photography is not permitted, I needed a fast zoom. I shoot all my pictures at f4 and the lens is fantastically sharp at all focal lengths. The lens is also extremely well built...

Optical quality is good in flare control and sharpness even at F4, but the colour is a bit "cool". The zoom range is useful.

After I bought my Nikkor 80-200 2.8 a few years ago I was enlightened by the luxury of fast lenses, but I needed that extra 100mm (beyond 200mm). I messed with the Sigma f/4 for awhile but the lack of a zoom hurt my shooting range. The Tokina looked...
