My review of the Canon EF 400mm F/4 DO IS USM Super Telephoto Lens. This is such a high quality super telephoto lens that I feel deserve a lot of praise. Here are some the reasons why I decided to acquire this lens.
FIXED FOCAL LENGTH - I have used other zoom telephoto lens for action, wildlife and adventure shots and I realized that I do not like to adjust the focal length when preparing to shoot pictures. My personal preference is that the time it takes to adjust the zoom ring takes too long and I tend to miss more great shots when my subjects are constantly moving. Learning how to spot my subjects through the 'tunnel vision' of my viewfinder has trained my eye to quickly subjects quicker than viewing my subject at lower focal length and then adjust to get the closest shot possible. In addition, in most instances, I almost always prefer to shoot at the maximum focal length anyway. I felt that 400mm was a great medium focal length between 300mm (Not willing to lower standard down to 300mm or less) or 500mm (Lens cost way more) or more. With my APS-C crop sensor (1.6x) with my 7D Mark II, I effectively already have 640mm and with my 1.4x Mark II, I can already reach 896mm.
WEIGHT - The EF 400mm F/4 DO IS USM is the best Canon lightweight lens with a maximum aperture of F/4. Although I have owned the legendary EF 400mm F/5.6, I feel the DO version is in a way the successor and provides better performance despite concerns about softness. At a little over 4lbs, you can practically hand hold your camera and lens for extended periods of time compared to the bigger 500, 600 and 800mm lens. But to compare apples to apples, when you stack EF 400mm F/4 DO vs. the EF 400mm F/2.8 L version, the latter is a heavier beast weighing nearly 9lbs, instead of 4lbs of the former lens mentioned. This weight difference was a critical reason why I choose the F/4 DO version. Although some will say that the L version is optically better, (I don't disagree) It also hard to say the F/4 is inferior. This lens can be sharp as a tack with the right AF system with the right camera body.
DESIGN & QUALITY
The design and quality of this lens like many other Canon Super Telephoto Lenses are built far ahead of their time and built to last a very long time. This lens is built like a NASA spaceship, not a tank; the quality is really that superior. The original inception of this lens is from 2001 and the particular version I own still works flawlessly. Every time I hold this beauty in my hands, I am always reminded of how happy to own such a superior piece of optical technology. I do like that fact that the 400mm F/4 has reinforced 'hooks' on both sides to attach straps when you prefer to wrap the lens around your shoulders when lens is not in use. The lens also comes with 52mm lens filter which is inserted at the back end instead of the front like most smaller lenses with frontal diameters of 82mm (EF 24-70mm II USM) or less. A tripod collar is included and it comes with a giant lens hood (ET-120) when attached makes the EF 400mm F/4 looks like the 'little big brother' of the famous EF 500mm IS II USM.
Thank you for reading!

Pros: Fast auto-focus, Superior build quality, Super-sharp images, lightweight, always ready on my camera
I've worked with this lens for about 6yrs now and it does not fail to deliver. Unlike most all of the other super-tele lenses, you will just carry this around with you like a walk around lens and it's out and ready to go. It gets used a lot because you don't think much about carrying it, it's that simple. Image quality on the 1Dx is outstanding and sharp. The only con I can see is the price went up since I bought mine.

Pros: Fast auto-focus, Superior build quality, Super-sharp images, great with 1.4 extender, very light in weight
In my opinion, this is a fantastic go-to lens for wildlife photography. Very lightweight and easily handheld, even for longer periods of time in the field. Most of the time, however, I have this lens mated to a 7D along with a 1.4x III attached to a pano-gimbal head/tripod combination. Outstanding reach for the money, and awesome, sharp results! Again, this lens can be handheld with a good keeper rate, but the effective focal length when used with extenders on a crop sensor camera body does cut into my success rate. On the other hand, especially with moving rather than still subjects, the ability to easily handle off a tripod has come in very, very handy for sudden action. The AF is fast and accurate and the 2-stage IS is reasonably helpful, too. Again, the 1.4xIII works great paired with this lens – much, much better than on my 300 f4. Perhaps a bit off on contrast (maybe) but I have not noticed a major issue with this, and certainly nothing requiring more than minor post edit. Prior to acquiring this lens I read everything I could find about it on the internet, which gave me some pause prior to taking the plunge. However, my actual results have been nothing short of fantastic, and I believe much of the negative, early reporting you can find on the internet must be one rumor or bad experience compounded by frequent repeat. I can recommend this lens without any hesitation. A fantastic package for hiking, traveling, every day use – again, a great way to get high quality reach at a comparatively great price.

Pros: Fast auto-focus, Superior build quality, Super-sharp images
I use it on a 7D often with a 1.4x converter. This is a splendid piece of equipment and this lens is very consistent, dependable and accurate when used hand held. I have adjusted a little more contrast and sharpness on camera and have achieved stellar results.Wonderful lens, just a pleasure to use.

Pros: very sharp, portable, fast
I've used this lens for several years, and in my opinion it is flawless. Whether hand held, tripod mounted, prime or with 1.4x or 2x extenders the performance has been superb. To my eye the sharpness and autofocus system compare to the 500 F/4 or 20-200 F/2.8, all stabilized.

Pros: Fast auto-focus, Super-sharp images, lightweight
Cons: expensive...but i'd buy an 800mm do in a nyc minut
I bought this lens for an African photo safari. I've used it there and in many other places over the past 5 years. This is the lens I carry mounted on the camera whenever I'm doing any kind of nature photography. Walking on a boardwalk behind 3 people equipped with 600 mm lenses, tripods, cameras etc. we all saw a hawk swoop into a pond catch a frog, land on a nearby branch , and proceed to eat it. I got the photo (handheld) with this lens, they got nothing...couldn't set up in time.

Pros: Superior build quality, Fast auto-focus
This lens is excellent. It is best when the length of a super telephoto is needed, but personal mobility is also a priority. It is just as compact and handles like the Canon EF 300mm f/2.8L IS USM. But has the reach like that of the massive Canon EF 400mm f/2.8L IS USM. It is great for wildlife, especially when traveling to national, state, and local parks where you may have to do some hiking to get to a certain shooting spot. This lens is also highly effective for outdoor sports. Image quality won't beat the "L" members of the super telephoto lenses, but it does come close and the images are highly useful for professional applications.
