Canon 2x EF Extender III (Teleconverter) Imported
The Canon Extender EF 2X III is designed for select Canon L-series telephoto lenses. The extender is perfect for photojournalists, nature and sports photographers who need to get close to distant and challenging subjects. The Extender EF 2x III increases the focal length of a lens by a factor of 2x while still delivering superb image quality. To ensure the best possible image quality in all shooting conditions, it also combines enhanced environmental protection, redesigned optics and improved data communication between lens and camera.
The extender allows professional photographers to shoot distant subjects without having to carry a number of heavy lenses. The Extender EF 2x III features five groups of nine elements, ensuring improved optical performance. All optical elements use Canon's Super Spectra coating, reducing ghosting and flare to minimize post-processing requirements. A new Fluorine Coating on the front and rear elements makes marks, such as spots left by water or fingerprints, much easier to clean than standard coatings.
To facilitate the accurate transfer of imaging data between the lens and camera body, the extender features an integrated processor which ensures all focusing, metering and ID information is available - allowing the photographer to capture crisp, well-exposed images. When combined with the latest range of premium Canon L-series lenses, these extenders enable higher AF accuracy, ensuring perfectly sharp shots, even when capturing moving subjects.
A carefully positioned lens release mechanism also makes it easy to mount the extenders quickly, reducing the time that the camera and lens are exposed to the environment. The extenders offer the exceptional build-quality expected from Canon's professional products, and are resistant to both dust and water, allowing photographers to use them in extreme shooting conditions.
Note: This teleconverter will only fit and work with a select list of lenses. Please click here for a compatibility chart of all compatible lenses.
Note: Autofocus will work only if the effective aperture is within the range of the camera (currently f/8 with most EOS cameras).

I bought this extender to use with the Canon 70-200 2.8L IS II. I decided to wait for this version rather than purchase the II. Maintaining sharp, contrast rich images of the 70-200 is important to me, so I figured Canon would improve upon the extender much like they did the 70-200.
I received the extender yesterday and had it installed between my 5D Mark 2 and the 70-200 very quickly.
Observations:
Images are slightly soft at f/5.6 (expected)
Images are surprisingly sharp and rich at f/8
AF seems to only work at the center AF point (expected)
AF much slower than without the extender (expected)
AF almost useless in low light (expected)
IS works like a charm (expected)
Conclusion:
For the occasions I need a longer lens than the 70-200, this extender will be a welcome tool. Compared to the cost of a dedicated 400mm lens, this is much easier to justify. Having near full use of AF (center point only) and IS makes this a no brainer for me.
Since I have not used the version II extender, I cannot compare the two. I am not sure if this adapter is worth the additional cost. If you like to have the latest and greatest and that psychologically improves your images, this is the extender for you.

I had never tried a 2X before, thinking it might be too good to be true. But with the new series III, I thought it might be OK on a high-quality prime lens. I went out for the day with my 7D and the 2x extender attached to a 500mm f4 IS lens. During the shooting (birds at considerable distance), I revelled in the closer view I was getting. However, back at the computer, I wasn't so happy. I am used to getting crisp feather detail on bird images, having learned good technique over about 5 years of serious practice with wildlife, shooting with Canon gear, most shots using the above 500mm lens with a 1.4X Extender. There was no crisp detail in any of the shots with the 2x. Even with ambitious post-processing from RAW, they were throwaway shots. The best single descriptor I had for the shots was "mush".
To be sure it wasn't just a bad day, I set up a controlled situation indoors. Mounted to a sturdy Gitzo tripod, with mirror locked up, etc., I took photos with just the 500mm lens mounted, then the 1.4X, then the 2.0X, all of the same subjects. Later I compared them on the computer, with the same results I got in the field; the 500mm results were sharp, the 1.4X a little less so but still very good, and the 2.0x result were garbage. Here was the decisive test: I resized the test photos from the 500mm alone by a factor of 2.0 in Photoshop, something no sane photographer would do to achieve a better result. However, the resulting images were sharper than those taken with the 2.0X extender. In short, the 2.0x not only did not provide and benefit, it was actually detrimental. I concluded I would get better results by shooting with the 500mm alone and cropping to fill the frame with the bird. Fortunately, I bought this from B&H rather than from someone on an on-line auction site or a lesser retail company. They took it back in a completely pleasant and business-like manner. Thank you, B&H.
This results still confuses me. The people at Canon are no dummies, so why would they make something that provides no benefit? I have no answer to that. It is just possible that I had a defective unit, so before you use this review alone to make your decision, search for others.

Comments about Canon 2x EF Extender III (Teleconverter):
Great lens. Very sharp. (see attached sample images). I wasn't expecting such sharpness from this teleconverter, but poor DOF (depth of field) @ f/11(even the background is sharp). That is one drawback of tele-converters. Also, i had to shoot Manual Focusing mode. The AF does not work with EF 2x III extender & EOS Rebel T2i series. Bummer. But this is definitely a keeper for natures shots and outdoor sports.

Comments about Canon 2x EF Extender III (Teleconverter):
I have owned the tc 2x II which was good, but this version seems a lot sharper and less CA, especially when used on a sharp lens to begin with. I am using it on a 70-200mm f4L IS with great results, even in the corners on zoomed in landscapes. The 1.4 version is supposed to be better, but I feel that going from a 200mm to a 280mm seems like a waste, like why bother? At least with the 2x you are doubling your focal length making any loss in quality worth it. If you have a very sharp lens to begin with I would recommend the version III lens over the version II.

Comments about Canon 2x EF Extender III (Teleconverter):
I matched this extender to a Canon 200mm f/1.8 lens
to achieve an effective 400mm f/3.5 range.
Shooting youth soccer league this combo gives a great length lens.
Images don't seem to have lost any quality
with the extender.
Was a little heavy & pricy but worth it.

Comments about Canon 2x EF Extender III (Teleconverter):
I use the extender on my 5D Mark II with the 70-200 2.8 lens. After being use to the 7D crop factor body, there simply was not enough reach at 200mm on a full frame body. Primary use is for outdoor baseball games
I've noticed the further you zoom, the more unsteady hand held photography is, so a tripod is suggested or increase shutter speed to stop image blur.
There is nothing bad about the extender, just remember that autofocus may not work on some slower lenses. The minimum Canon recommend is an aperture of 2.8, which gets stopped down to 5.6. Any value higher, and you lose autofocus.
The extender is perfect for people who have a good L Series lens and don't want to buy another to achieve more reach. Image quality is still very sharp, much sharper than cropping the image on your computer.

Comments about Canon 2x EF Extender III (Teleconverter):
I am finding that in low light this 2X EF Extender is in need of a tripod to get the sharper shot. Since I am using a 2.8 lens I am finding a loss of two stops as expected, throughout. I am thinking this extender might be best in higher light situations when you can use a faster shutter speed, and obtain a crisper image. All in all, it is fun to get in twice as close to the subject!

Comments about Canon 2x EF Extender III (Teleconverter):
I never had the 2x II, so can't compare with that, but this version III works very well.
But, it's not magic. As most already know, magnifying 2x means a decrease in optical speed and image quality. How tolerable the image quality decrease is depends on the lens and the camera's resolution.
On a 5D, attaching this to a 70-200mm f/2.8L IS II was still reasonable (one of the sharpest zooms on the biggest pixels), but was still not outresolving the sensor. On a 7D (smallest pixels), the same combo doesn't look so great.

Comments about Canon 2x EF Extender III (Teleconverter):
It will extend my 70-200 2.8 is lens to a 400 mm lens
it will extend lets say a 300 MM 2.8 Is lens to 600 mm at a much lower cost by thousands of dollars and pounds of weight lower than a 600 mm lens
Quite expensive compared to the Mark II but if it works out like the 70-200 2.8 IS mark II lens it is more than worth the high cost of this extender as the pictures that I have taken with the new 70-200 2.8 is mark II lens just blew my mind comparing the quality of the emprovement done to the old 2x extender to the new extender is well worth the extra dollars spent in the new extender

Comments about Canon 2x EF Extender III (Teleconverter):
This is a great alternative to buying a 400 or 600mm lens. You do lose a bit in the f-stop but at that focal length you can still get the nice bokeh with the extender. The quality of the image isn't as great as it would be with a fixed lens, but for the amount you spend on it its a fair trade.
