Tamron SP AF 300mm f/2.8 LD (IF) Reviews
ShutterBug reviews the Tamron SP AF 300mm f/2.8 LD (IF) and writes;
“Two large elements–the first two in the formula–of Low Dispersion (LD) glass effectively correct chromatic aberration, including secondary spectrum, ensuring high sharpness plus freedom from comatic flare and color fringing even at f/2.8.. In the f/5.6 to f/8 range of apertures, image quality was even higher: absolutely superb. The results of my field tests confirm suitably high contrast, too, and little flare even in backlighting, evidence of a well designed lens hood and internal precautions.”

Tamron SP AF 300mm f/2.8 LD (IF) Specifications
Tamron’s fast telephoto SP AF300mm F/2.8 LD (IF) delivers remarkable and exacting performance demanded by professionals. Two large LD (Low Dispersion) elements in the front lens group provide high contrast and crystal-clear image quality from the full open aperture. With Internal Focusing, you can maintain optimum holding balance since the lens’ overall length remains constant during focusing.
The Floating Focusing System improves optical performance especially at close shooting distances. Nine specially-shaped aperture blades form a nearly perfect circle to create excellent background blur for outdoor portraits. The true value of this lens is apparent when photographing sports action, low light theater performances, and wildlife.New is a Canon version that provides an easy-to-use AF/MF focusing ring, rear filter insertion frame that is compatible with the standard accessory circular polarizing filter and with the ring rotation capability from outside the lens, and detachable tripod mounting stand.
Switching between AF and MF is easily accomplished by sliding the focus ring back and forth. Manually focusing is smooth and precise with the focusing ring.
