Sigma 50-500mm f/4-6.3 EX RF HSM Lens for Nikon SLR Cameras Review

Average Reviews:

(More customer reviews)This is was my first Sigma EX HSM lens.The 50-500mm was just too good to pass up for the price.While I've had other Sigma lens I purchased them mostly for the price.The quality was OK/acceptable.But these EX HSM (Hyper Sonic Motor) lens are the finest quality lens I've ever put my hands on!They are mostly metal vs mostly plastic.They are smooth as silk and extremely FAST focus.They seem not to seach back and forth as much for the focal point--they lock on almost immediately.This lens makes brilliant true color shots and works great with my Nikon D100.With the digital camera 1.4x factor this lens is like having a 70-700 on a film camera.The only note is the lens is HEAVY like as in 4lbs!You really can't imagine it until you mount it on the camera and shoot--you'll need a mono/tripod for using the 500mm. The lens comes with a beautiful case and a high-tech lens shade.You'll never buy anything but a Sigma HSM lens again.Too bad they don't make the HSM for all their models.

Product Description:
Encompassing all popular focal lengths from the 50mm "normal" to 500mm ultra- telephoto, the Sigma 50-500mm f4-f6.3 EX RF HSM hyperzoom lens gives you amazing versatility, plus a 10:1 zoom ratio, while its rear focus system ensures fast, convenient manual focus. The use of an apochromatic design plus four optical elements composed of special low dispersion (SLD) glass, a seven-group zoom system, and multicoated optics combine to give you high-quality images.
This lens, featuring Sigma's silent hypersonic motor (HSM) focusing system, allows you to shoot pictures of your subject without the normal noise of an automatic focus system. In addition to its quiet, responsive AF function, you can also use the full-time manual focus at any time. The zoom lock mechanism helps reduce the "zoom creep" distortion that can occur when your lens is tilted up or down.
Sigma used magnesium in the tripod mount to help reduce the weight of the lens, just over 65 ounces, yet still it still maintains the strength and rigidity necessary to support the lens's weight. This model is dedicated to Nikon AF SLR cameras.
