  • Multi-Layer Diffractive Optical Element
  • Two-Mode Image Stabilization System

The EF 400mm f/4 DO IS USM Lens from Canon utilizes multi-layer diffractive optical (DO) lens technology to correct chromatic aberrations, substantially reduce lens size and provide excellent overall telephoto image quality. This offers an alternative for sports, nature and wildlife photographers, giving exemplary results in a size previously unheard of for a lens of such a focal length and aperture.

In addition, Image Stabilization provides up to 2-stops of correction against camera shake for less blur when using slower shutter speeds. Furthermore, with two distinct stabilization modes are featured. Mode 1 is best used with still subjects while Mode 2 is optimized for panning with moving subjects. An ultrasonic autofocus motor (USM) enables fast, smooth and quiet AF action and the AF stop buttons allow you to temporarily pause autofocus. Also, to minimize autofocus time with specific subjects, a focusing range limiter function lets you set the distances at which the lens will focus and with manual focus override, you can apply precise manual focus at any time, even in AF mode.

With a barrel constructed of magnesium alloy, the lens is designed to be lightweight and durable and a tight seal structure ensures effective dust-proof and drip-proof performance. A detachable, rotating tripod collar provides a stable mount to tripods or monopods and the drop-in Gelatin Filter Holder 52 comes with a glass filter and fits standard gelatin filters. This lens includes a dedicated lens hood and hard carrying case and is compatible with the optional EF 1.4x II and EF 2.0x II extenders. 

  

High-diffraction optics suppress aberrations and provide class-leading low size and weight
Two-stage image stabilization; dual-axis camera shake correction or vertical axis only(for panning)
AF Stop function pauses autofocus when an obstruction appears

    I use this lens for wildlife photography and as my review headline states this lens is portable and excellent. The automatic focus is fast and accurate. The images are sharp at f/4. I prefer to shot at f/5.6 or higher when possible. It is more forgiving and gives me a higher percentage of in focus images.

    I did my comparisons between the 400 f/4, and my 70-200 f/2.8L IS USM and 70-200 f/4L IS USM with the 1.4x EF III Teleconverter mounted to the 70-200's on my 5D MK lll. As many of you know the 70-200 f/4L with the 1.4x III converter is tack sharp with beautiful color and it was the best of the three. The pleasant surprise was the close second with the 70-200 f/2.8L IS or the 400 f/4. The 400 f/4 delivers excellent sharpness and color. In conjunction with its relatively light weight and fast accurate autofocus this makes for a great 400mm telephoto field lens.

    The field kit I put together is the 400 f/4 IS DO and the Canon T3i (600D) with a form factor of 1.6. This results in a 640mm lens and camera body weighing in at about 5.42 lb. This allows me to carry the lens and get some great hand held shots. When I get tired a monopod is perfect and keeps me going. The image quality remains excellent with this kit. By the way just to throw some numbers around if I add my 1.4x III Teleconverter to the mix I end up with 896mm of reach and the overall image quality is very good.

    One last comment. I have read other reviews expressing concern about this lens having a lack of contrast. I can only say that every current digital Canon EOS camera body is internally adjustable by sharpness, contrast, saturation, and color. Any refinements an image may need out of the camera can be quickly accomplished in post processing. Don't give this a second thought.

    I have been an L glass shooter with all of my Canon bodies (all full frame format) and pained over this decision for years. Don't hesitate to try the Diffractive Optics (DO) glass. It delivers excellent images and you can carry it with you and that means you get the images the guys on the road side or in the parking lot never saw.

    I've owned the 400 DO for 4 years opting for the light weight and easy handling. It replaced a 500 f4 IS Canon lens that was excellent but heavy for me.
    The DO isn't as sharp as the 500 and that is my major complaint. I recently purchased a new 500 (like the one I sold for the 400) and am pleased with photo quality.

    The switch for the A-F and IS project from the barrel and are easily moved during handling. Canon could fix this easily. The lens rotation in the mounting ring is inferior to Canon's other big tele's. For the price of the lens I would expect the same smoothness. There is no de-tent to "feel" when the lens is rotated 90 degrees, for instance.

    I use it primarily for wildlife, mostly birds.
    I have been using it primarily to follow 2 eagle nests paired with the 2x 111 extender to give me 800mm and autofocus. I also use it at short range, 12 feet +/- for hummingbirds.

          Comments about Canon EF 400mm f/4 DO IS USM Lens:

          I will be going on an African safari later this year. The luggage weight restriction is a major challenge for this trip. After doing quite a bit of research and evaluating the pros (lightweight and small for a super telephoto prime, relatively fast autofocus that's compatible with 1.4 III tube) and the cons (image quality and contrast) of this lens, I purchased it with reluctance and hesitation. After receiving this lens, I went to the zoo and was very pleased with the images I captured. I've tried this lens on two camera bodies – 5D II and 7D. The images on the 5D II were sharp and contrast doesn't seem to be an issue. I also got great results on the 7D (not to mention a better reach due to the crop sensor). So if you're thinking about getting a Canon 400mm f/4.0 DO, go for it.

            With a 2X extension can get outstanding shots with Tripod - but looses AF with the Extension tube.

              Like others, I was justifying the DO vs the 'L' series lens. This lens is light, very sharp & fast. I shoot kids, sports & birds with this lens & am very happy with the results. I stop the aperture down to F5 for tack sharp images of birds, & open it to F4 only when needed as it can be a little softer. Still quite sharp at F4 though. Contrast is good, I add extra post production no matter which lens I use. Detail & colour are as good if not better than my other L lens. Buy this for the portability for handheld shots at 400mm

              Comments about Canon EF 400mm f/4 DO IS USM Lens:

              I rented this (and may end up purchasing it), and had a chance to compare it in the field with the Canon 300 mm f/2.8.

              Both these lenses are about the same diameter (100 mm, hence f/2.8 for the 300 mm, and f/4.0 for the 400 mm). The 400 mm is lighter and shorter than the 300 mm, and works wonderfully hand-held. (As long as you are careful and use a high enough shutter speed).

              Focusing was pleasingly fast with a 5D Mk II, and it was just a joy to use in the field. I appreciated the longer reach of the 400 mm compared to the 300 mm for birds and other wildlife.

              I found two problems with this lens, when used for wildlife photos.

              1) It doesn't focus as close as you would like for small birds, lizards and other wildlife. I couldn't fill the frame with a warbler, and had to step back to take the picture.

              2) There is a pronounced "bloom" (flare, I guess) when photographing bright subjects against a dark background. For instance, a white egret in the sun against a shadowy background had much lower contrast than it should. The latter problem can be fixed to a large extent in processing, but it really is annoying when everything else about this lens is so perfect.

              I found no problems with sharpness or chromatic aberration in my use, but didn't do any formal tests.

                I bought this lens two weeks ago and have been extremely pleased with the results. It replaced a 100 - 400 Canon lens and I should have made the move much sooner.
                Forget about the reviews that claim this lens is soft, IT IS NOT.
                I have used this lens for wildlife hand held and then used my 500 f4 Canon on a tripod. The 400 DO held it's own in this field comparison.
                This lens is light enough for occasional had held shots and travels well in my back pack.
                I am pleased and can't wait to try it with the Canon 1D X.

                  I have used this lens extensively both hand held and on a tripod including with a 1. 4 III teleconverter. This lens is sharp! I love it in every way. I have travelled extensively throughout Southeast Alaska in my boat and the portability of this lens allowed images I could not possibly have obtained otherwise. I really don't have an opinion about contrast, other than once I have enhanced my photos in Lightroom, the images are consistent with other L lenses I've owned and used. Amazing technology and I wish Canon would release a 600 f4 DO. It would be my next lens. Weight really is a major factor with these big lenses.

                    I'm an old lady wildlife photographer. I've begun to have shoulder problems from carrying a regular 500mm lens with 1.4x converter, tripod and DSLR with a 1.6 crop factor.

                    When my husband pointed out this lens, i was hesitant. Those crisp, wonderful photos with our big lenses are so special. But I've been delighted. Tiny birds a long way away hanging on cliff walls are sharp. Birds just a few yards away are just as detailed as with the bigger lenses. Still, with the 1.4x converter, this lens is ONLY the equivalent of 560mm. So I still love to shoot with the 500m and converter close to the car. But when it comes to carrying into the field, this is definitely my lens of choice.

                    Comments about Canon EF 400mm f/4 DO IS USM Lens:

                    Like I did, you're probably reading reviews for this lens because you are trying to figure out whether a non L-seies lens is worth the price tag, and if this diffractive optics experiment was a good thing.

                    First, the weight reduction. As others have pointed out, it is several pounds lighter (in some cases half the weight) compared to other telephotos of comparable focal length. To be able to hand hold (especially in the field, if you're after wildlife shots) is great, and at this weight one could keep it up for extended periods. Using this on a 5D Mk II. Tracking a heron in flight was not an issue.

                    Second, it does not seem flimsy. Seals are more than adequate. Some have noted issues with the assembly coming loose, but I can't see it so far. Time will tell. IS works well.

                    Thirdly, and the big question: image quality. It's really, really good. Focus is quick and dead on. Colors are true. Detail is retained very well. Bumping contrast in your RAW program, or via your favorite Photoshop technique, fully compensates for any softening the DO might have caused. This point is largely overstated by detractors. No lens flare issues seen.

                    It's a wonderful lens, and I'm quite happy with it. On pins and needles from the order placement until my first trip out with it, but now that I've seen what it can do firsthand, I'm not looking back. This thing comes out with me on hikes from now on.

                      Used for wildlife shoots

                      Pros: easy to handhold with 1.4x giving a 900mm equivalent.
                      Great IS
                      Relatively lightweight
                      very fast autofocus
                      Perfect for handheld wildlife shoots

                      Cons: price, price, price (oh - did I n=mention the price :))

                      I'm using this lens for primarily wildlife photography. I wanted a lens which travels well including in small commercial aircraft. I'm using a 1.4 extender with a Mark IIID. While have not had a chance to use the lens in the field, I have been using it in a limited fashion. It appears to have the portability and clarity needed to perform the intended tasks. The clarity of the captures are remarkable. The carrying case is provides substantial protection.

                      I think overall Canon did it right with this lens. If it was lighter in weight I would be happier, but isn't that always the complaint with any 400 lens?

                      Comments about Canon EF 400mm f/4 DO IS USM Lens:

                      This lens is my very favorite for wildlife photography (mainly birds). I say this having owned Canon telephotos since the manual focus days (400mm f/4.5 SSC) and having tried many of Canon's current L Tele lenses (100-400mm L zoom, 300mm f/4 L, 500mm f/4 L).

                      The 400mm DO is very sharp and produces great color. the "knock" on this lens is that it produces lower contrast than non-DO Canon L telephotos and I do see this is my shots taken in flat light. However, this can readily be adjusted in Photoshop and is not an issue when shooting in contrasty light. Most importantly, the 400 DO will get you shots that larger and/or heavier teles will not allow you to get. The 400mm DO weighs 4.27 pounds, while the other Canon "big tells" are as follows:

                      Canon 300mm f/2.8 L: 5.61 pounds
                      Canon 400mm f/2.8 L: 11.81 pounds
                      Canon 500mm f/4 L: 8.53 pounds
                      Canon 600mm f/4 L: 11.8 pounds
                      Canon 800mm f/5.6 L: 9.9 pounds

                      Put simply, the 400mm DO is wonderfully hand holdable while the other lenses are not. Yes, the 300mm f/2.8 L is probably light enough but 300mm is usually not enough for the birds I am shooting. I find the 400mm DO is very easy to use when shooting birds in flight! In fact, I have frequently shot my 400mm DO alongside other photographers who were using the Canon 500mm f/4 L. More often than not, if the action requires to take the camera off the tripod, I get the shot and they do not. In summary, I cannot overemphasize how useable and portable this lens really is (easy to get in suitcase or on an airplane too).

                      The 400mm DO also does very well with the Canon 1.4x Extender III. This combination with on my 7D camera is just a joy to use.

                        I've only owned the lens a short time so it will worth a follow up review after a year or so. Initial impressions are favorable. It is a pleasure to use because of the size and weight. I have owned the 600 f4 and 500 f4. Probably not a better lens on the planet than the 600 but it's a monster :). I use this lens on a 50D (1.6 crop factor), which makes it seem longer than it is. For large and medium wading birds, it is great. For mammmals, great. Sharpness was excellent and I had no contrast problems. I process incoming RAW files in Lightroom 3.3 and it is easy.

Before, it was my 600mm that came with me but as many are aware, it is a very heavy lens. The quality of my images are fantastic and I am looking forward to using it much more in the future.

                              Comments about Canon EF 400mm f/4 DO IS USM Lens:

                              I debated between this lens, the 500 f4, and 300 f2.8. I do a lot of walking around shooting wildlife and I have back issues so weight was a very big factor in my choice. I rented this lens first to test it out and then decided to purchase as this was the lightest weight of the three options. I find it very easy to carry in the field for long walks. The naked lens is very sharp. It also takes a 1.4x TC well. I have read reviews that the 500 f4 is sharper with the 1.4x TC but the 400 DO with 1.4x is still quite sharp enough for my taste.

                              The autofocus is very quick to lock on for birds in flight if the delimiter is set for the longer distance. This is true even with the 1.4x TC.

                              With the 11.5 ft minimum focusing distance I find with the 1.4x TC that I can still fill the frame with a subject as small as a chickadee.

                              I have owned the lens for 10 weeks and use it on a 7D body.

                              I have had a 500mm f/4 L for several years. However, it is really hard to hand-hold that lens for any length of time, and increasingly hard to travel with it with the increasing baggage weight restrictions on airlines. I got the 400 DO about four months ago, mainly for wildlife photography here and overseas and I love it. It is easy to handhold and pack for travel. Rather than trying to pack the heavy tripod & Wimberly gimbal I use for the 500, I rely on hand-holding & bean bag for the 400 + 1.4X TC, and if really needed, it is light enough to use my Velbon carbon-fiber spotting scope tripod. Because I have the lens with me, I am getting far more, super-sharp photos.
