Canon 400mm f/4.0 Overview

  • 1Description

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
Two-stage focus limiter function allows focusing within a range of 11.5' to infinity (full range) or 26.2' to infinity.
Full-time manual focus override
Dust & moisture resistance made exceptional by magnesium alloy lens barrel, tight seal structure and new rear gasket at lens mount
Detachable, rotatable tripod collar and drop-in gelatin filter holder

Canon 400mm f/4.0 Reviews

EF 400mm f/4 DO IS USM Lens is rated 4.7 out of 5 by 32.
Rated 4 out of 5 by from Pleased with this lens 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.

Rated 5 out of 5 by from An Unexpected Pleasure 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.

Rated 5 out of 5 by from Excellent Portable Lens 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.

Rated 5 out of 5 by from Great Lens Terrific for Handheld or tripod bird photos or wildlife. On a Canon 7D - has great reach while giving very good detail and bokeh With a 2X extension can get outstanding shots with Tripod - but looses AF with the Extension tube.

Rated 5 out of 5 by from Great lens 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

Rated 4 out of 5 by from Very sharp, but be careful with contrast 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.

Does this lens have autofocus with the EF 2x III extender?
Asked by: Anonymous
When using the 400mm f/4 with the 2X III Extender, you will retain autofocus with the 1D series and the 5D III with the newer firmware. With all other cameras, autofocus will be lost.
