Tamron SP 300mm f/2.8 LD (IF) Telephoto Manual Focus Lens with Case, Hood & 43mm UV Filter - 6 Year USA Warranty, Adaptall-2 Camera Adapter Required.

An ultra-high performance, fast telephoto lens to meet the needs of the most demanding professional photographers. This lens is well suited to the fast-action world of sports photography, but the lens' bright viewfinder image and fast aperture lends itself excellently to shooting indoor theatrical events. The nine-blade aperture design makes a nearly circular opening for a soft blurred background-an ideal effect for portraiture. Two large LD elements incorporated in the optical design produce sharp, clear pictures with high contrast and true color fidelity from corner-to-corner.
