Product Description

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..

This review is from: Sigma 50-500mm f/4-6.3 EX DG HSM APO RF Telephoto Zoom Lens for Sigma SLR Cameras (Electronics)

I have a Nikon d80 and d70. I also have a 27 to 70mm lens as well as a 70mm to 300mm. There really isn't a lot of positive impact to go from 300mm to 500mm ... at least, not as much as I had hoped. The lens itself is fast and the focus is accurate. It IS a very heavy lens and anything beyond 250mm requires at least a monopod or at best, a tripod. I am enjoying the lens but expected just a bit more for the size.
