Canon EF 800mm f/5.6L IS USM Super Telephoto Lens—Canon’s Longest Telephoto Lens At Large

         If you think Canon had already released the ‘longest’ lens available under their care, then you would probably be right. But then how long is this ‘longest Canon lens’? And how much would it cost to have one? To answer the first question, Canon EF 800mm f/5.6L IS USM Super Telephoto Lens, Canon’s pride when it comes to length, is 18.1 inches long. And the prize? We will find out soon.

        Canon EF 800mm f/5.6L IS USM Super Telephoto Lens is a professional L series lens released by Canon in June 2008. This lens was made with a magnesium alloy body and mount and with plastic extremities and switches. The material was used to enhance its light weight. In fact, despite its obvious length, it is lighter compared to some of Canon’s line-up by more or less 10 lbs.

        Features of this lens are: a wide rubber focus ring that is damped, a focus distance window, the ability to limit the focus range, a focus-preset mechanism, an image stabilizer that is effective up to four stops and is tripod sensing, an AF stop switch, and weather sealing. A maximum aperture of f/5.6 gives this lens the ability to create depth of field effects. The optical construction of this lens contains two fluorite lens elements, and "Super UD" (Ultra low Dispersion) and UD Lens elements. This lens uses an inner focusing system powered by a ring type USM motor. This lens is compatible with the Canon Extender EF teleconverters.

        This lens is a good choice for any long-distance shots like outdoor sports, wildlife, news photojournalism and more.

        One of the main points of this lens is its image stabilizer, providing up to 4 stops of correction for camera shake. This makes it even more practical in many situations not to mention the superb photographs it can produce. Although it has slight flaws that are forgivable, seeing he kind of image it can produce would make everyone forget about those flaws. It photographs well even in the dark when compared to other lenses.
