The EF 200-400mm f/4L IS USM Lens with Internal 1.4x Extender from Canon is a high-performance super-telephoto zoom lens with a built-in 1.4x extender that converts the focal range and maximum aperture to 280-560mm f/5.6. The extender is located at the base of the lens and applied with a simple lever switch. The EF 200-400mm f/4L IS USM Lens features one Fluorite and four Ultra-low Dispersion optical elements that deliver sharper images with fewer chromatic aberrations. Super-spectra lens coatings minimize ghosting and flare and a Fluorine coating on the front and rear lens elements keep oily smears and fingerprints to a minimum.
From the Manufacturer
EF 200–400mm f/4L IS USM Extender 1.4X
Designed to satisfy the discriminating needs of sports and wildlife photographers, the EF 200–400mm f/4L IS USM Extender 1.4X is a high-performance super telephoto zoom lens with an optically matched built-in 1.4x extender for maximum versatility. With a simple flick of a switch, the zoom range can be quickly increased to 280–560mm (f/5.6). This capability is extremely useful in applications where it is not possible to change lenses quickly, while also protecting delicate equipment such as a digital SLR camera’s image sensor in environments with dust and high humidity. The EF 200–400mm f/4L IS USM Extender 1.4X incorporates one fluorite and four UD lens elements, which provide excellent correction of chromatic aberration throughout the entire zoom range for professional quality images with high resolution, contrast and color fidelity, while a 9-blade circular aperture helps deliver beautiful, soft backgrounds. It utilizes inner focusing, ring USM, a high-speed CPU and optimized AF algorithms for fast and accurate autofocusing. And, with Power Focus mode, focus shifts are quiet and smooth, which is essential for filmmaking. Image stabilization is effective up to four shutter speed steps, with three image stabilization modes (standard, panning, and during exposure only) providing excellent results for a wide range of subjects. Optimized lens placement and coatings deliver outstanding color balance, while helping to minimize ghosting and flare. The lens is highly resistant to dust and water, enabling shooting even in harsh conditions. A fluorine coating on front and rear lens surfaces repels dust particles and makes the lens easier to clean.

Owning this lens eliminates most of the needs of several others. Need 200-800mm range or anything in between, this lens has you covered. To get to the 800mm length, you need to add a 1.4x teleconverter + the internal 1.4x and use either a 5d III or a 1D series body. I have achieved excellent results using the 1.4x internal and an external 1.4x teleconverter.
If you own other superteles, owning this lens will definately make you rack your brain deciding if you need that 300mm 2.8 IS II, 400mm 2.8 IS II, 500mm IS II, or even the 600mm IS II. This lens can pretty much match them in the IQ department.
Yes it is expensive but like most things in life, you usually get what you pay for.
There are 4 buttons surrounding the lens toward the front. You can press any of those buttons and lock the focus for 10 seconds which has worked great with some of my rodeo pictures and jumping photos.
The lens comes in a heavy, sturdy suitcase.....Yes the lens is heavy, but I carry it in a Tamrac long lens backpack that carries the lens attached to the camera at the same time. With my Canon 1Dx and the 200-400mm lens together, the total weight is 15 lbs. I have been mounting it on a Monostat Monopod with a Really Right Stuff Monopod head and Really Right Stuff Long Lens Support System for added stability. I also have used it on a RRS Gimbal Head which makes it much easier to handle for birding. All and all, this has become my favorite lens. The quality of images really blows me away. I will try to post some images if I can figure out how to do it....
Since purchasing this lens, and living in the Highlands of Scotland, it has become a much used favourite lens and is used in conjunction with the 24-70L II and the 70-200L II for alternative versions of the same subjects. All three of these lenses deliver the same levels of sharpness in practice. The otherwise excellent EF300L prime has been retained for rapid hand holding when the required stability cannot be provided for the 200-400mm f/4L.
In actual use, the new lens is certainly as sharp as the other lenses mentioned above but is also far more demanding in its use. It requires absolute stability to achieve best or even adequate results. This has been achieved by wrapping strips of rubber draft excluder around the hood which enables the car roof or other handy objects to be used for stability without damaging either the lens body or the support. This is far quicker and more stable than using a tripod.
Using this simple but effective technique, recent images taken of a ferry going across the local river at just under 2 miles were so sharp that the registration plates of the vehicles could easily be read. The images were so sharp that the customer, for whom the images were taken, could not use them as they felt it breached data confidentiality. I provide this as a simple example of how sharp this lens can be when used with total stability in real life situations.
What it cannot do well is take images of moving objects such as birds in flight or anything from a moving object like a ship. The lens is simply too long and heavy for accurate hand use and tripods are inappropriate. I would suggest that such hand holding use is unlikely to work well in practice because of the lack of required stability and that may explain the reservations made elsewhere. Other lenses of varying lengths are easier to use and likely to achieve better results when used via hand holding.
This review has been specifically provided to tackle the question of sharpness which has been questioned by some. It needs to be stressed that this is a difficult and demanding lens to use and that its use requires particularly secure stability at maximum magnifications especially.
However, provided great care is taken to provide total stability as suggested, it can produce stunning results as described. I would therefore suggest that any lack of sharpness is a problem of user stability rather than lens function.

I used the lens on a 5D Mark III and was very happy with the overall quality and the performance of the mode 3 IS on the lens worked out great. I did take some photos hand held that turned out fine, however in general this was a lens that I needed to use on a monopod.
Given that I am an amateur photographer doing swim meet photos for fun for my daughter and her team, this is not a lens that I would buy. However, if I did this on a regular basis ( and was paid for it ) I would consider it.
