Canon Rebel T3 Telephoto lenses made by Sigma that have a Sigma HSM focus motor

"I was completely surprised at the focus accuracy - not a single miss-focus due to the lens. Autofocus was more than fast enough for action shots. This lens is very sharp and with the speed and accuracy of the autofocus it can easily be used for close sport events. Built quality is very good. Macro is excellent, as expected. The mount and hood that comes with the lens is a huge plus."
