This is was my thrid Sigma EX HSM lens. 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 24-50 on a film camera. While with telephoto lens this is like getting extra lens for free--with wide angles you loose a bit. But that is the camera's fault not the lens. 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.
