I got this lens as a gift from my mother. It is the best gift ever. It is very heavy and you need a tripod to use with it. I tried using a mono-pod, but had better results/luck on a tripod. I am not sure Arnold Schwarzenegger could hand-hold this one...

Resolution has always been my highest priority and this lens certainly is the best. The auto-focus features are superb. After using the 600mm f/4 L lens for years trading it in for the 800 was the best trade I've ever made. It is lighter, a longer...

I am a very armature photographer and the shot's I got with this lens makes me look like a pro.

ITS GREAT...I LOVE IT... ITS GREAT FOR SPORTS OR TRAVELING

I have been taking wild life photos for 30 years with canon lenses and the new 800 is a great improvment over the old FD 800 , if the picture is a thousand word it speeks for it self

I have used the 800 to shoot the worlds fastest motorcycles on the Bonneville Salt Flats. In five days I shoot over 7500 images. I hand hold the 800mm to shoot at 1/500 to 1/640 late in the day and use a mono-pod to rest it in between shots. Images of...

The images of the moon with this, is unreal!! I can't believe what I was watching. The photos were so close, it looks as if I were standing right in front of it. Every concealable detail was exposed, AWSOME!!!!

Hmmmm, where to start. My job as a photojournalist and my hobby as an aviation photographer depend on good equipment. No ifs, ands or buts about it. The image stabilized Canon 800mm F5.6 is a photographers dream. It is relatively lightweight for the...

This lens is a dream come true. I shoot wildlife, often at a distance, and this lens is amazing. The lens is sharp as a tack and, when mounted on a gimbal head, very easy to handle. Auto Focus is super fast and quiet. Used a 2X converter and had great...
