Sigma 300-800mm f5.6 EX IF APO HSM Ultra Telephoto Zoom Lens

The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.

Sigma 300-800mm f5.6 EX IF APO HSM Ultra Telephoto Zoom Lens

This lens covers the telephoto range from 300mm to the ultra-telephoto range up to 800mm. By continuously varying the angle of view from 8.2 to 3.1, the lens takes a lot of the footwork out of picture composition.

The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance.

Two ELD glass elements in the front lens elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast.

The Hyper Sonic Motor (HSM) models provide silent, high-speed and precise auto-focusing with full time manual focus override.

HSM means this lens will autofocus on Nikon D40/D40x, Nikon D60, Nikon D3000, Nikon D3100 and the Nikon D5000 DX Cameras

It also features a drop-in 46mm filter holder in the rear part of the lens barrel, which can be rotated to facilitate the use of filters, including a polarizing filter.

Since focusing and zooming do not change its overall length, this lens is easy to hold and use. In addition, since the front of the lens does not rotate, a circular polarizing filter can be easily attached and used.

When this lens is used with the 1.4x EX or 2x EX Apo Tele Converters (optional), it becomes a 420-1120mmF8 MF lens or a 600-1600mm F11 MF lens respectively.

The SIGMONSTER, April 1, 2008

By Michael A. Hays "dustmite" (Morgantown, WV United States)

This is an awesome lens and is a real must-have for birdwatching and other nature photography. The zoom range is extremely flexible and the f-stop reasonably fast, but keep in mind that this is a very, very specialized lens. First of all, yes, it is gigantic! This is not something you'll be carrying around day-to-day. It can be very challenging to get sharp pictures at focal lengths beyond 400mm or so. You MUST MUST MUST use a sturdy, high-end tripod and gimbal head. This will also preclude the "downward fall" described in another review. The lens alone is very heavy, and once you toss in a sturdy tripod you're talking 25+ pounds of equipment at a minimum; this is really going to limit your mobility and affect the way you shoot. It takes a lot of forethought to use this lens, but I prefer to think of that as an advantage.

When used properly, this lens has fantastic image quality -- very sharp, excellent contrast. When I say sharp, I am talking L-series sharp, even wide open. The HSM focus speed is fast, perhaps slightly slower than Canon's USM but not appreciably so. The only thing it's really missing is image stabilization (or optical stabilization, as Sigma calls it), which would really help out on those long shots. This is a minor limitation, though, to a great lens. If you have the discipline to learn how to use this lens properly (and if you can afford it!), you'll reap some great rewards.

Very expensive, Very heavy, only "fair" photo quality, March 29, 2008

By David E. Carter (Sanibel, FL)

I bought this product with high hopes. I saw the price, saw the length of the lens, then hoped to be able to get some great nature photos. I used this produce only 5-6 times, all with some difficulty, as the weight of the lens alone is around 15 pounds. Add a heavy Nikon D1 camera, and the tripod has to support nearly 20 pounds.

Getting a good photo was difficult, even with a remote shutter control. Just getting the camera/lens to stay focused on the subject was tough, as the heavy lens kept falling, slowly falling forward. The real disappointment came when i downloaded the photos to my computer. I got a few shots of eagles nesting close to where I live, but they were nowhere near as good as I had hoped for.

I paid about $7,000 for this lens, including shipping. I would have never have paid that much for the results I got, had I knows in advance. $2,500? Yes. Over $7,000. No. Save your money.
