About Sigma

This high zoom ratio lens is optimized for digital SLR cameras and capable of covering a wide range of focal lengths from 50mm standard to 500mm ultra telephoto. This ultra-zoom lens employs a seven-group zoom system, which provides a high zoom magnification of 10x. Triple-cam Rear Focusing System ensures high precision throughout the whole focus range.

The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance.

This lens uses four pieces of SLD (the special low dispersion) glass for excellent correction of color aberration. A zoom lock switch eliminates "zoom creep" during transportation, a convenient addition when traveling. The HSM Hyper Sonic Motor models provide quiet high-speed AF function, as well as full-time manual focus capability., The rear focus mechanism produces a non-rotating front lens elementwhich accepts a bayonet "Petal-type Hood", which prevents extraneous light from degrading the image quality.

By adding an APO teleconverter (sold separately), you can use this lens as a 140-700 .... ..7.3-8.8 MF ultra-telephoto zoom lens with a 1.4X EX teleconverter, or as a 200-1000mm F10.4-12.6 MF ultra-telephoto zoom lens with a 2X teleconverter. ..Teleconverters can be used in 100mm 500mm focal length range..

I've had the lens for a month and used it for wildlife mostly. Pictures are clear and up-close. The weight didn't bother me as I expected it to be heavy with a lens of this size. The kit lenses are made of plastic and feather light, but don't compare in construction as the Sigma lens. I like the fact that in auto focus you can also fine tune it with the focus ring manually.

It takes a little more light than the more expensive lenses, but I expected that as well and for the price, it is a good purchase. To get a lens with this focal length and light weight would cost considerably more. I am very pleased with the lens.

Great Buy

I bought this lens at the beginning of the summer, and i couldn't be more happy. i haven't gotten to use it as much as i'd like, but so far it works great hooked to my E-500. it is a little heavy, but what do you expect from such a large focal length? i shot an airshow hand held without image stabilization and i am very pleased with the performance.

I'm glad I bought it.

I work in the Middle East so I can’t always get close to what I want to take pictures of. Some of my shots are as far away as 3-5 miles. With this lens I can get a view of it. It's not up close and personal but I can make it out, granted my objects are huge to start with. But anything within normal range I can get fantastic pictures with this lens as long as I can keep the camera still. I would recommend a good unipod, tripod or a stable surface to brace yourself on with this lens; it does get heavy after a while.

The wait was well worth it.

For the nature shots that I do, the lens is a fine piece of equipment. It definitely needs a sturdy tripod for crisp focus. The autofocus works well in the spot mode, but tends to shift easily at full magnification.
