Sigma 50-150mm f2.8 EX DC OS HSM APO Lens for Canon
This Sigma lens is a gemit's packed full of features yet still priced at right around $1,000, which makes it excellent for enthusiasts that may not have a big gear budget. The 50-150mm range is a nice mid-range on a full frame camera, or it can be used as an 80-240mm lens on a crop sensor. The f2.8 aperture is rare for the zoom range and the price, and combined with a nine blade aperture, results in an excellent depth of field. Optical image stabilizationa must for any good telephotoallows for shooting at up to four speeds slower without image shake. Sigma also included their Hyper Sonic Motor for quiet, yet fast, autofocusing. Coatings and glass elements help reduce distortion for sharp images. Like most telephotos, it's a bit heavy, weighing it at just under three pounds.
