 "Wonderful lens! You'll take it with you everywhere." 2008-11-08
By Marcelo Clerici (Palo Alto, CA)
I hesitated for weeks before buying this lens. It's expensive (only $1,000 or so cheaper than the wonderful 400mm 2.8 Canon lens), it's 4.0 instead of 2.8, it's not an L lens (since it uses the less common diffractive optics), and the user reviews of the early production lenses were mixed (the latter reviews are much better). However, I finally decided to buy because I needed a 400mm lens for a mix of sports and outdoors photos, and I knew that I would rarely use the much heavier and longer 400mm 2.8 lens. It is true that the 400mm 2.8 has photographic advantages over the 400mm 4.0 DO, but those don't mean anything if you don't have the lens with you when you need it!



In the month or so I've had the 400mm DO, I've taken it with me on trips--in planes, inside the cabin, with enough space for two camera bodies, and 24-70mm and 70-200mm zoom lenses--and I've shot sports handheld _exclusively_. The autofocus is very fast, the image quality is _astounding_, and I can only say good things about this lens. Perfect 10 for me!

 "Light enough for a walk-around" 2008-08-23

This is an often maligned lens, due to its high cost and the lower contrast compared to regular lenses. Both are true and the latter is easily fixable in the digital workflow. The upside that no other lens can compete with is, that one can carry it for miles without undue strain, handhold for substantial periods of time, like waiting a few minutes for some wildlife to move into position, or for some sports action to happen. Obviously, there are even lighter 400mm lenses, but those have typically no image stabilization and a very small maximum aperture.

At this point for me, this is my one size fits all super telephoto lens. There are sharper lenses, longer lenses, faster lenses, etc. but this one can do almost everything, and do it good enough.

 "The best 400mm lens to carry outback" 2006-11-14
By Mark W. Bohrer (Saratoga, California)
This is my lens for handheld images of birds in flight. It's sharp and exhibits no color fringing or other chromatic aberration. By comparison, my Leitz 400mm f/6.8 Telyt shows a fair amount of color fringing outside the center region. To be fair, the Telyt is a much simpler design.



The Telyt does have higher contrast than the EF 400mm f/4 DO IS, but a levels layer in Photoshop can fix that.



The 400mm f/4 DO IS is much lighter than any 400mm f/4 lens with conventional optics. DO lenses have a diffraction element that compensates for the color dispersion of spherical lens elements. It also reduces optical complexity and size.



The f/4 speed makes autofocus faster, and allows even better isolation of subjects using narrow depth of field. While bigger and heavier than Canon's 400mm f/5.6L, the f/4 lens is light enough at 4.3 pounds that it's still easy to carry. I've used mine on hikes above 10,000 feet to photograph bighorn sheep.



IS definitely makes a difference handheld, and on a tripod below 1/125 second. Canon's 400mm f/5.6L is a non-stabilized lens.



I've taken some of my sharpest wildlife images with this lens - you can see every feather in some bird shots. Highly recommended if you can afford one.

 "The BEST lens in my bag... Do not let the nay-sayers scare you off!" 2009-12-04
By Alan Taylor (Chicago, IL United States)
I bought this lens when it was first released back in 2006. After three and a half years of use, I find it consistently the most used lens in my camera bag. Quite importantly, I haven't personally experienced any of the negatives I've read in other reviews. Not once. The pictures I am able to capture with this lens are nothing less than superb in quality. The lens is very well built and feels totally solid - built like a truck. Of course, the size of this lens is clearly the most amazing feature. Even fully extended, the zoom is quite significantly shorter than a 200mm standard zoom lens, therefore calling very little attention to itself. The images I've been able to get with this lens are amazing. It's feels well balanced on the front of my 30D. Easy to handle, and easy to swap out if you need a shorter focal length. Think about all of the pictures you can capture when you can have 300mm worth of zoom on your camera without lugging around a huge, sometimes inappropriate feeling lens. Though certainly quite a significant investment, this lens has been worth every penny I spent on it. If you're in the market for a premium zoom lens and this baby fits in your budget, I highly recommend this lens. You'll absolutely love it.

 "zoom creep" 2009-10-12
By kc
I'm very disappointed with the lens creep on this lens. I realize this is typical of a longer zoom lens, but was hoping that Canon would have addressed this problem with a lens of this expense. The zoom had almost too much resistance for the first few shootings, but now it is impossible to shoot upward or downward and stay in focus. (I've only had the lens a few months.)

 "Awesome Results" 2009-08-17
By Rajendra Yadav (Pune, Maharashtra India)
Before purchasing Canon EF 70-300 DO IS USM Lens, I was using 75-200 Canon lens which was without image stabiliser. So, without tripod, I was unable to take good pictures. When I bought this lens and used it at different locations, I got awesome results of the lens. I do not use tripod. Its a worth buying. You can see some of the pictures taken by me on this page. Thanks to amazon.

 "Amazing" 2009-05-04
By Dave (Pensacola)
I purchased this lens because I do a lot of candids and 200mm is just not good enough. I also recently purchased a 5D MkII, so any praise I may have for the lens may be partly due to this camera. When I read some reviews of this lens, I was worried that it was weird. I will mostly address these issues. Is it heavy? No. I use a monopod and hand carry a 100-400 lens without problems. This lens is only 52 mm at the front,so it has amazing reach for its size. Does the zoom feel heavy? No. The zoom needs some resistance, since the front of the lens would extend by itself if it was too light on the zoom control. This is the same issue you have with the Sigma 18-200, another great all purpose lens for candid shots. Both lenses have a lock button that keeps the lens from extending when you not taking pictures.

Lastly and most importantly does the diffraction type lens cause any problems? No. I have literaly seen no problems with lack of sharpness or unusual flare. I think you would have to shoot tripod test scenes to reveal this. Using a monopod in real life conditions,the issue does not appear to exist. Admitedly with back ligthting you can get some fogginess and flare,but this is just like other lenses. I think some ot the reviwers who are critical spend too much time bench testing. When I am doing candid,or travel photography,especially with a full frame camera,this may become my main lens.
