This is lens do everything

Excerpt: This lens is amazing, delivery quality image as any prime lens, plus the feature that let you work in composition. This lens (200-400 f4) do the job of 200mm,300mm and 400mm primes 2.8mm. The only difference is the aperture (a little more than 1.2mm less of those three). Using late canon model cameras as 1D X or 5D Mark III, that is not problem. I feel this lens is a new generation of photographer's gear.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: Took it out immediately and shot with internal and external Extender(784mm-f13-1/1250-ISO1000-5DMkiii), I figured this should stretch the test. If I wasn't pleased it was going back! I kept it and am thrilled with the performance. The sharpness blew me away!
Summary: The question is whether this lens will get you shots you never could have gotten without it. I own the 500mm f4 and lose shots because I don't have it with me or I'm not sure that the focal length will be right. Now I get those shots with a top notch lens. It is spectacularly sharp and fast, well built and great looking. Things I don't love... can't take the lens foot off. That is a real pain and interferes with handholding.
Summary: I am a professional photographer and just used this lens to shoot the Super Bowl in New Jersey, courtesy our local Canon rep. All I can say is wow. If it weren't for the out-of-reach price tag I would own this lens. For sports, it is almost perfect. It is fast, versatile and when a play is running into the end zone the ability to change focal length at a fixed aperture is amazing.
Canon throws a monkey wrench into the big white lens game.

Summary: I have used this lens all over the U.S. and Eastern Africa as well. Performance of the lens is top notch as to be expected by the price tag. It's not light, but it's not too heavy either. It is probably canon's most versatile lens outside of the 70-200mm 2.8 IS II. Owning this lens eliminates most of the needs of several others. Need 200-800mm range or anything in between, this lens has you covered.
Summary: Excellent optics, beyond ridiculous price. This lens offers optics broadly equivalent to the Nikon 200-400 but costs almost twice the price. That is insane. Whilst with this lens you're stuck with a 1.4 teleconverter the Nikon can use up to a 2.0 and still autofocus using a d800 or a d4 and get, again, almost identical quality as with this lens using a 1.4 internal converter.
Very sharp imaging but requires more care to achieve good result than most in practical working situations

Summary: The downside of this lens is obviously the cost and that is an unavoidable issue that each individual will have to weigh up considering the possible use. This review however is intended to address the issue of whether the use of a lens with incorporated extender compromises sharpness of imaging as some have suggested.
Summary: I recently bought this lens and after the first 500 shots am thoroughly impressed with what Canon has been able to accomplish. While possible to handhold this lens and get decent results with image stabilization, this lens shines on a tripod with a good gimbal head. Images taken with a 5d Mark III are contrast-y and sharp, even at 560mm with the 1.4x extender engaged. Autofocus is quick and accurate.
Conclusion: Best lens I've ever used for aviation photography. All of the versatility needed to capture images in any setting, and the built-in converter loses almost nothing I can detect in terms of image quality or focusing speed. Extremely sharp, extremely versatile, and built ruggedly for travel to rugged places.
Pros: Fast auto-focus, Superior build quality, Super-sharp images, very verstaile telephoto range, built-in teleconverter
