About Canon 800mm F/5.6L

This is the longest telephoto lens among Canon's lineup and a terrific choice for any long-distance application-outdoor sports, wildlife, news photojournalism and so on. It's actually lighter than Canon'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'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's image stabilized, providing up to 4 stops of correction for camera shake. This makes it even more practical in many situations.

Just amazing

Shoot it on a bean bag, lay it on a fencepost in a pinch. It is all sharp. It is the the most amazing piece of glass I have ever seen. In 5 months, the shots from this lens have eclipsed all before. It is great for very shy animals like wolves and birds. I can't wait to try it with an extension tube. The 7D is made for this lens.

Crystal Clear and Sharp


from Oakland, CA  -  Photo Enthusiast

I use the lens to shoot local wildlife. I can reach more now with 800mm without add the extension any more. It focus super quick and accurate. I love it so much. It crystal clear and sharp. Yes, you can briefly handhold for short time to shoot birds in flight. This lens is not easy for travel. It is big and heavy.


Amazing Super Telephoto Lens


from Chennai, India  -  Photo Enthusiast

I have been using this lens for more than a month now. Its really exciting to see distant birds and wild animals so close thro' the image finder. AF is very fast.


Sharp, fast, incredible lens


from Parkland, FL  -  Photo Enthusiast

Great with the 1DMkIV. This combo allows captures I would not have previously been able to capture, particularly birds in flight.

Engineered Excellence


from Rapperswil, Switzerland  -  Photo Enthusiast

This lens exhibits superior picture quality and is thorough sharp without any chromatic aberration. It's not cheap but it's worth every penny! Simply a "must have" for an enthusiastic wildlife photographer. The built-in image stabilizer provides sufficient support for excellent picture quality without using a tripod. However, I recommend the usage of a gimbal head to make this lens virtually weightless.

New Canon 800 f/5.6 IS super telephoto


from Chino Hills, Ca  -  Semi-pro Photographer

This lens while expensive is unbelievable for wildlife. It is fast and incredibly sharp at its maximum aperture of 5.6. Amazing if you have the bucks.

Birder's Delight


from Seattle & San Jose del Cabo, BCS, Mexico  -  Photo Enthusiast

I bought this lens for bird photography and use it on my Canon 7D which is a great combo. Before I was using a 500mm f4 IS with a 1.4 extender. I hand carry using a sling made by Blackrapid[@]which screws into the tripod foot and allows me to center the weight across my shoulder with the lens upside down. This allows me to hold the foot like a big handle which takes some of the weight off and keep it from swinging as I walk. I like the 800mm reach without having to use the extender on my 500mm but this adds a couple of lbs and I've lost 3' of focus (16 vs 19). Bottom line, the quality of my shots have improved and I have adjusted to carrying the weight and now carry a 2nd 7D with a 100-400mm zoom for close up shots when they present themselves. At age 62, I was worried that the extra couple of lbs would be a big negative. I do feel the extra lbs but really only notice when rotating to shoot vertically. Lastly, while a tripod would no doubt give more reliable results, I find that hand carrying is the only way to go when practicing my bird photography. Being able to walk and almost instantly swing into action is the only way to take the action to the birds as opposed to setting up in a static manner and hope that they come to you.

Dream Lens


from Florida Keys  -  Hobbyist/Enthusiast

Beautiful piece of equipment, both functionally and physically.Had the 500mm f/4.0 IS lens and must admit it was and is a great lens with spectacular I.Q.I found I needed more reach and didn't want to keep attatching and removing my 1.4 and 2x extenders in the field.This lens gives me the reach I desire without sacrificing any image degradation that might be caused by the use of extenders.With this bare lens and drop-in circular polarizer the sunrise, daytime and sunset images are stunning.Shy birds and wildlife are no longer frightened away by trying to get closer to them while more docile subjects can be framed and shot up close with gorgeous background blur.This lens, even though it is 9.9 lbs., doesn't feel much heavier to carry around than the 500mm did.I have it mounted on a Canon 5D Mark II, Wimberley 200 II gimbal head and an Induro 414A tripod. This set-up renders the lens and camera virtually weightless. I know I've found the lens that I will be most using for a long time[...]

JON P  Purchased by the dealer from another country outside of the US - same product but will NOT have a USA warranty. Will save you some bucks if are planning on getting an extended warranty through the dealer anyway or if the dealer offers the same warranty as the manufacturer would have offered.
