Canon EF 300mm f/2.8L IS USM Reviews

Photo.net reviews the Canon EF 300mm f/2.8L IS USM and writes;
“It is capable of producing professional-quality images when used with the EF 2x teleconverter. This autofocusing 600/5.6 combination was my standard lens for bird photography until I bought my 600/4 in August, 1994. When combined with the EF 1.4x teleconverter, the resulting 420/4 combination is fast and very sharp.”

SLRGear reviews the Canon EF 300mm f/2.8L IS USM and writes;
“Performance on a full-frame 5D is equally impressive. The lens is really challenged by the full-frame sensor, with 1.5 blur units in the central region and just shy of 2 blur units in the corners at ƒ/2.8. This kind of performance is the norm through to ƒ/11, not getting any better or worse; at ƒ/11 things even out somewhat and you get a consistent 1.5 blur units across the frame. It never hits the ”tack-sharp” results we saw on the sub-frame 20D, but the results are still excellent. “

The-digital-picture reviews the Canon EF 300mm f/2.8L IS USM and writes;
“All other image quality aspects of this lens are excellent as well – color and contrast are superb. A fluorite element and two UD-glass elements are very successfully utilized to correct CA (Chromatic Aberration). Light fall-off is minor and rather even at f/2.8 on a full frame body. Distortion is negligible, flare is well controlled.”

Features & Specifications

Canon EF 300mm f/2.8L IS USM Specifications

The high-performance L-series EF 300mm super-telephoto lens is a terrific choice for sports photographers and other long-distance users. Sports action requires a fast shutter speed and a long focal length. This lens easily complies thanks to its large maximum aperture–which supports a faster shutter speed–and its 300mm length.

The lens also boasts a built-in, dual-mode Image Stabilizer (IS) function. This creates an equivalent shutter speed of up to four stops faster than the same size lens without an image stabilizer, letting you capture long distance hand-held shots far more assuredly. And thanks to the fluorite element and pair of UD-glass elements, the lens effectively corrects the chromatic aberrations that are prone to occur with telephoto lenses.

Other features include the world’s fastest autofocus (AF) speed with an improved Ring Ultrasonic Motor (USM) and new algorithms; a rugged, lightweight magnesium alloy lens barrel; and a detachable tripod collar that removes smoothly and locks securely. All Canon lenses carry a one-year warranty.
