Excellent Lens

My company specializes in high altitude photography we recently replaced our legacy lenses with this masterpiece of optical engineering.
If you are hand holding a lens longer than 200mm this is the only lens you will ever need. Its compact DO design is ideal for action photography. With little to no chromatic aberrations, this large aperture lens offers all of the perks of the modern Canon Super Telephoto Lens with none of the draw backs of size and weight. At home in your hand or on a tripod this lens will lens will make your old 400mm f/5.6 nothing more than a paper weight.
If you have concerns about its DO design based on a previous Canon product that was received poorly, abandon your doubts, This lens is the real deal and will push you over the top. Able to full resolve a 5.5um pixel pitch it is fast, light, and creates stunning images.
I would recommend this to a friend!

I purchased this lens over a year ago. Extremely satisfied with the results. The overall performance of this lens is in line with its MTF charts - superb! The portability of this lens is second to none. It did not disappoint.

Superb sharpness even with Mk III 2X extender. Works great with mono-pod for fast paced sports. If it wasn't for the price, I would have bought it long ago.

400mm DO II for bird photography

I bought this lens used and it far surpasses my expectations. It is as close to perfect in terms of resolution and color as you can get. Using it wide open produces phenomenal images and the same is true when coupled with the 1.4x and 2x tele extenders. Much easier to carry than my old 500mm f4.

Extremely sharp and very easy to handle

Purchased this lens to replace my EF300mm F2.8LIS and my EF500mm F4IS. Wanted to go lighter and this lens was right in the middle of the 2 focal lengths and saved me a ton of weight. Optically I think this lens is right there with my 300mm and sharper than my 500mm. Sharp with excellent contrast along with very good background rendition. It takes the 1.4 and 2X teleconverters and remains very sharp and still focuses quite well. I have nothing but praise for the lens.

My company rented this lens for me for the Breeders' Cup. This lens hit it out of the ball park. Light weight, no distortion, amazing photos! Plan to put this on my wish list

Close but no cigar!

Would prefer a f3.5 version of the DO lens. Because of price, plus size and weight, It would soon become the most popular telephoto for wildlife, just as it was for many years with Nikon. You wouldn't think a half a stop would make much of a difference, but it greatly reduces the size when compared to the f2.8, plus the sharpness and low light capability and versatility would be improved over the f4. With the emphasis on making tele lenses lighter, yet more shock resistant, it is also convenient for backcountry and air travel. Adding a 1.4x teleconverter to the f3.5 lens is a convenient combination for doing wildlife, yet the speed of the lens is still very reasonable to work with in subdued light. Canon, please bring back a smaller, lighter version of this classic and very popular f3.5 lens!
No, I would not recommend this to a friend.
