- + Идеальное фокусное расстояние для фотоохоты,спорта. Качество на высоте,легко крутится колесо зума(с легкостью одним пальцем)
- - Тяжеловат(3700г) немного устала рука держать 2 периода хоккейного матча,на 400мм 4.0 мягковат,ДОРОГО!!!
- + Удобство пользования. Малый вес (по сравнению с другими супер зумами). Встроенный конвертер очень удобно. В связи с этим- относительная универсальность объектива.
- - Основной недостаток этого стекла- завышенная цена. Простой смертный не может себе позволить такую игрушку. Не маловажный недостаток- это невозможность кропа. То есть готовый кадр уже сильно не порежешь. Я сравниваю с 400\2.8. Тот...
- + Исключительно высокое качество изображения, резкость на уровне EF 70-200 f/2.8L IS II, умеренный вес (при таких габаритах!), встроенный экстендер 1.4х, возможно использовать внешние экстендеры вместе с внутренним, отличный стабилизатор, почти на 5 стопов.
- - Цена, но что вы хотели за такую уникальную линзу? :)
The 200-400 image quality is good, but not uppermost in the Canon line. I'd describe the lens as sharp without the TC engaged; and sharpness to fall off modestly but measurably once the 1.4 is engaged. I would not place sharpness with the 70-200 II, however. There is little comparison, in my mind, between sharpness and rendition of the 200-400 and the 200/2 or 300/2.8 - but that comparison may not be a fair one. The 200-400 is quite contrasty, and color rendition is vibrant. I'd go so far as to say that the lens *has a look*.
Auto focus speed is good and AF is decisive on the 1Dx, but definitely not what we enjoy on the current 2.8 zooms or large aperture telephoto primes. 200-400 AF and IS are considerably better, however, than the 100-400 as you would expect them to be. The 200-400 IS is excellent, and the Mode-3 tripod IS is a pleasure to use. Several times I unintentionally engaged the internal 1.4, because of what I'd call either a design flaw in the TC Lock or a possible defect in our rental copy's Lock. The lock was completely reliable in keeping the TC from becoming disengaged, however. Lens weight and apparent bulk are high, but balance is decent with a 1Dx mounted. In the 3500 images I recorded, the was an even distribution of hand-held, monopod and tripod use. I'd need to be able to workup to handholding the 200-400 all day long.
The reason to own the 200-400 relates to the shots you *won't* miss by virtue of its zoom function over this FL range at f4. In the work I do, a subject simply moves out of the frame when a long prime is in use, or is too far away when a shorter FL was loaded. So lots of images are possible by avoiding fixed FL lenses. Clearly this is not a novel thought, and such logic could be applied to any zoom lens - but it's of special meaning here by virtue of what FL are being covered at f4. An internal 1.4 simply expands this principle a notch further, and the many (dirty) steps that are eliminated by allowing the 1.4 to live permanently inside the lens package are meaningful. One can't help but guess that internal TC's will appear in upcoming products. There is talk that this lens *pays for itself* by eliminating two or more expensive prime telephoto lenses from your collection. I really can't subscribe to this argument for my work, but your experience may certainly vary. With this in mind, you may find a 100-400/1.4 external TC quite liberating financially...
All of this begging the question of what dollar value is reasonably assigned to this group of attributes and tradeoffs. Were cost of no concern, I'd certainly buy the 200-400, even given the above caveats. I can live with the weight, image quality and AF with the knowledge that I'll succeed getting images that I'd miss with any other lens or combination of lenses. Cost being a priority, though, has me appreciating the long-in-tooth 100-400 for what it is and what it isn't; and contemplating buying a used Nikon 200-400 (at a bit more than a third the Canon's cost) and a D800.
Trite to say, but what we really need is a modernized 100-400 at, say, under $3500. That will sell, sell, sell!

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.

Things I don't love... can't take the lens foot off. That is a real pain and interferes with handholding. It's not Canon's fault b/c of the big TC, but it is something that I find annoying. With that in the way, using the zoom ring becomes a bit more challenging. I have my own way of doing this, but it's not as natural. Also, it's expensive - but it'll hold it's value, so I view my ownership of the lens as more of a rental. After a year or two, my time with the lens is pure profit knowing what folks will pay for it.
Things I love... knowing that I can reach more than 500mm at any time, composing as I wish. Very happy with that.

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....

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.




very heavy for traveling , takes an amazing shots . its a must have for outdoors . i traveled the world with it
