<p>  This is the longest telephoto lens among Canon&#8217;s lineup, and a terrific choice for any long-distance application-outdoor sports, wildlife, news photojournalism, and so on. It&#8217;s actually lighter than Canon&#8217;s EF 600mm f/4L IS lens, weighing just under 10 lbs. It uses a refined optical design, with two fluorite lens elements, one UD element, and one Super-UD-glass element, for outstanding correction of color fringing and superb contrast and sharpness. This super-telephoto lens uses magnesium-alloy barrel construction to enhance its light weight, and has weather-resistant gaskets throughout for use in harsh conditions. It&#8217;s compatible with both the EF 1.4x II and 2x II tele extenders for even more reach: EOS cameras with 45 AF points will continue to provide autofocus at the center AF point when the lens is used with the 1.4x extender. Finally, it&#8217;s image stabilized, providing up to 4 stops of correction for camera shake. This makes it even more practical in many situation <a href="http://www.amazon.com/Canon-800mm-Telephoto-Digital-Cameras/dp/B00132FXOW/ref=sr_1_16/176-8725161-0802631?ie=UTF8&#038;s=electronics&#038;qid=1262157436&#038;sr=8-16?ie=UTF8&#038;tag=httpwwwsageim-20" title="More at Amazon">(more&#8230;)</a></p>

<p>  This ultra telephoto zoom lens offers a fast aperture of F2.8 at the 500mm focal length and F5.6 at the 1000mm. It covers widely-used focal lengths from 200mm to 500mm and has a large aperture of F2.8 throughout the entire zoom range. This lens can be used to create amazing image expression with various types of photography such as astrophotography, portraits, wildlife, sports. SLD (Special Low Dispersion) glass and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all type of aberrations. The super multi-layer coating reduces flare and ghosting and provides high image quality from the extremely large aperture. The lens hood, designed exclusively for this lens, blocks out extraneous light. A 72mm filter can be inserted at the rear of the lens, and a circular polarizing filter can be used in situ thanks to the ingenious internal rotation mechanism. The dedicated Li-ion battery BP-21 is used to power the zooming and AF operation.

This lens can be used to create amazing image expression with various types of photography such as astrophotography, portraits, wildlife, sports. SLD (Special Low Dispersion) glass and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all type of aberrations. The super multi-layer coating reduces flare and ghosting and provides high image quality from the extremely large aperture. The lens hood, designed exclusively for this lens, blocks out extraneous light. A 72mm filter can be inserted at the rear of the lens, and a circular polarizing filter can be used in situ thanks to the ingenious internal rotation mechanism. The dedicated Li-ion battery BP-21 is used to power the zooming and AF operation.

<p>  A Opteka High Definition 500mm preset telephoto lens is great for nature and sports photography. The amazing power of this lens gives you the equivalent of looking through a pair of 10x power binoculars. It has a manual preset diaphragm, a rotating tripod mounting collar and a soft lens pouch. Because all Opteka lenses are designed and manufactured with the highest possible degree of consistency, you can swap lenses mid-shoot with no discernable variation in color or effect. The unprecedented purity, color saturation and repeatability of Opteka lenses virtually eliminate the need for lab color timing corrections caused by other lenses. This puts more creative control where it belongs, in your hands.
