Canon EF 200-400mm f/4L IS USM Extender 1.4X Lens Review
Before I tell you all about this amazing piece of photographic equipment, let me start by putting your mind at ease. I will not even try convincing you into dropping $12,000 on a lens, especially a $12,000 lens that doesn’t even carry itself, or compose, capture, and process images for you. For the money they’re asking, you would expect at least that and perhaps a few more features to boot.
So you can take a deep breath, relax, and read on without any undue anxiety or pressure. I can’t promise that I won’t make you like the lens, but I do promise not to say you need it. With apologies to Robert Hunter, my job here is only to shed light, not to master.
Canon first announced this lens to the public in February of 2011 and after 2 agonizing years of delays and technical setbacks, it finally came to market earlier this spring. It was well worth the wait. This was Canon’s answer to Nikon’s comparable zoom lens, except Canon not only matched their 200-400mm with constant f/4 maximum aperture, they upped the ante by incorporating an internal 1.4x extender too.
Last month, I brought the new Canon EF 200-400mm f/4L IS USM Extender 1.4X to Bosque del Apache National Wildlife Reserve in New Mexico. Here is my mostly subjective, non-technical review and initial thoughts.
TALE OF THE TAPE
The lens is 14.4 inches (36.6 centimeters) long without the hood and weighs in just a hair under 8 pounds (3.6 kilograms) – twice as long and 5 pounds heavier than the Canon EF 100-400mm f4.5-5.6 USM, in case you thinking about upgrading within that similar focal range. If you are one of these people, you might also want to consider a sturdier tripod and a gimbal head as well. In terms of physical size alone, it compares best to the Canon 500mm f/4L IS II, with the 200-400mm being a pound heavier but an inch shorter.
Since getting my hands on this lens, the question I been asked most often, surprisingly, is whether it is “handholdable.” I suppose it is, but what lens isn’t – if only for extremely short durations of time? For a quick, spontaneous grab shot of Sasquatch, I guess I could say yes. For serious, critically sharp wildlife and sports imagery, I would recommend a good tripod or monopod.
While shooting at Bosque, my new lens and I were somewhat marginalized by the insufferable birder crowd and their phalanx of mammoth 600mm and 800mm super telephotos. I paid them little mind and quietly went about my business as each of the photographers tried their best to steal a furtive glance my way in order to get a better look at this new species of Canon glass. Soon enough, one of the sports walked over and asked if he could check it out, which he dutifully did. After which, in a rather condescending tone, he declared to everyone within earshot that it was “a nice little lens.” I do have to give him some credit for withholding the patronizing pat on my head.
My initial impression when I first lifted in from its case? Heavy, solid, stout, like a little fire hydrant.

Internal 1.4x Extender
This new feature is what separates this particular lens from all the others, including the comparable model used by my Nikon brothers and sisters. The built-in 1.4x optical extender expands the focal range as far out as 560mm with a simple flip of a lever. You can almost think of it as two lenses in one: a 200-400mm f/4 and a 280-560mm f/5.6 with an impressive total focal range of 200-560mm without a single lens change (That’s an eye-popping 320-896mm on a Canon APS-C sensor camera!).
The extender lever is substantial and not at all flimsy like I feared it might be. There’s an audible “clunk” when the extender is engaged that is solid and reassuring, unlike most clunking sounds that emanate from expensive, high tech toys. It operates beautifully.
The 200-400mm f/4L offers lightening-quick, smooth, and incredibly accurate autofocus capabilities for Canon EOS cameras. The lens focuses so fast and so effortlessly, that you literally cannot see it happening in the viewfinder. For bird-in-flight shots, I often didn’t know if the results would be in focus or not since the camera and lens locked on and fired simultaneously as well as instantaneously. Not until I reviewed the images shortly afterward was I able to confirm that they all were, in fact, tack sharp. There was no waiting for focus to be confirmed. It just happened without me knowing it!

Canon claims there are four stops of shake correction incorporated in the Image Stabilization (IS) system of this lens. I can only take them at their word on this since I wouldn’t know how to accurately verify the claim anyway. At any rate, it’s useful to know that this lens has three IS modes: Standard, Panning and Exposure Only.
Standard mode (Mode 1) mitigates vibrations in every direction and is most effective when shooting subjects that aren’t moving very much. Panning mode (Mode 2) corrects vertical or horizontal shake depending on the direction of the panning. For example, when panning horizontally with a moving subject, this lens stabilizes movement vertically and vice versa. Exposure Only mode (Mode 3) corrects camera shake only at the precise moment of exposure so focus tracking is easier. This would be most useful when tracking a very fast or erratically moving subject.
Of course you can choose not to use IS at all and it can be easily disabled at anytime.
This lens uses a 9-blade circular aperture design, which creates soft, dreamy, out-of-focus backgrounds when using large apertures. This effect makes your primary subject seem to jump right off the page – or computer screen, an illusion many wildlife and sport shooters try hard to emulate. This particular claim I can see and verify with my own eyes. It’s downright dreamy.
Aside from the questions about its size and hand holding ability, the next concern on everyone’s mind is lens sharpness. Folks who are super obsessed with sharpness tend to gravitate toward primes anyway so their questions about this telephoto zoom are overtly loaded with suspicion. Now I like sharpness as much as the next guy but I’m not one of those people who toss and turn at night worrying about micro resolution, lines per inch and circles of confusion and the like. Maybe I should, but I don’t.
With that being said however, my 20-plus years of experience gives me a pretty good subjective yet accurate view of image quality and I can say that it’s pretty damned sharp – both with the extender and without. I didn’t test the lens at the smaller apertures (and who would care?) but from f/4 to f/11, it was super sharp from corner to corner at all focal lengths. Don’t trust me? Take a look at the mind blowing MTF charts on Canon’s webpage:
Then again, maybe you should just trust me on this one.
There are four ultra-low dispersion lens elements and one fluorite element that makes chromatic aberrations with this lens almost non-existent. There’s also a fluorine coating on both the front and rear lens surfaces, which is apparently a good thing too.
Like all Canon L-series lenses, the 200-400mm f/4L is impervious to almost any weather Mother Nature can throw at you. It’s moisture and dust resistant, ready for shooting in the harshest of conditions.
At Bosque, I shot in an hour-long, steady downpour one afternoon and after I wiped the lens down with a dry towel, there was no water inside the lens barrel, no condensation, and no fogging up. The same couldn’t be said of the photographer, however.
Is the lens “worth” it? Who the heck knows? It will be worth it to some photographers and certainly not worth it to others. As a professional nature and wildlife photographer, it’s the lens I’ve waiting on for a long time. It’s the ultimate wildlife lens, period. But I knew that 2 years ago before I ever got my hands on it. The only question was whether Canon delivered a clunker or hit the home run with the finished product. It appears to be the latter.
The only other worthwhile alternates to this lens are the 400, 500, and 600mm primes coupled with 1.4x and 2x extenders. But the flexibility of zooming for creative compositions and framing make the 200-400 with internal 1.4X extender a no-brainer for me. Wildlife photography is more than getting the longest focal length and tightest crop possible on an animal. Sometimes you want to fill the frame with the subject and sometimes you want to incorporate some of the environment. Sometimes the subject is too close and you miss opportunities while switching lenses, changing cameras, or adding and removing tele-extenders. This lens solves those problems.
