Excerpt: Primary use is for nature/wildlife photography. Prior to purchase I considered and tested the EF 400 F2.8 and the EF 400 DO F4 lens. The high versatility of the 200mm to 560mm range offered by this lens was the major decision factor in purchasing this lens. I took delivery just before the peak of the spring warbler migration and have shot ~2000 pictures over the last four weeks. The picture quality is awesome and my ratio of quality shots has significantly improved.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh, Strong Construction
Excerpt: I use this lens for all sports, and it is ideal. the zoom gives it great range, especially for football and baseball, and the built-in extender just adds to that. It's easy to operate, with all of the switches being easy to use without looking. As for the performance, it's the usual top drawer Canon quality. With this lens and the Canon 70-200, you can cover any field of play and any sport. It's a beast of a price, but if you are serious about your shots, it's worth it.
Pros: Consistent Output, Fast / accurate auto-focus, Nice Bokeh
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.
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.
Excerpt: This lens is extremely sharp thoughout the zoom range, and is still very sharp when the 1.4x extender is engaged.<br /><br />I replaced my 300mm, 400mm and 500mm primes with this lens and have been very happy with the results. Always being ready to compose an action scene with the correct focal length is great versatility.
Pros: Consistent Output, Rugged, Strong Construction
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.
