Product Description:

This extender has been re-designed optically and offers excellent performance with compatible EF lenses (same as the Extender EF 1.4x II). It features a new seven-element design, and same weather-resistant design and anti-reflection internal construction as the new EF 1.4x II. The EF 2x II doubles the focal length of any lens it's mounted to, and reduces its effective aperture by two stops. With the EF 2x II, AF is possible with any EOS body if the lens has an f/2.8 or faster maximum aperture, and compatible Image Stabilization lenses maintain the IS feature when used with any current EOS camera.

Does the job, but at a price2010-03-13
I have to say, the extender does do the job...it will get you closer to the thing you want to capture, but the quality just isn't so great. It turned my 70-200mm 2.8L IS into a much much lower quality lens. The price is right, so if you don't care too much about the quality loss, this is the way to go. For me, I'm returning the extender to get the Canon 100-400 4.5-5.6L IS. Lots more money, but I think it's worth it.

Works As Expected2010-03-07
As the other reviewers have said, it is a nice option to have in your bag. It is not meant for everyday use to get that incredibly sharp, close-up of birds, animals or people. It is very helpful when the shot is very difficult to make without it.

If you examine the sample pictures in Amazon under the Canon EF 2X II Extender Telephoto Accessory, you will see the Shuttle Discovery taken with a Canon XT1, Canon 100-400mm, and the 2X at about 4 miles. This was without a tripod, through the shimmering heat of the Florida day, and with the salt air from a windy day causing a lot of haze.

I could have just relied on the 100-400 at maximum and enlarged and cropped later. It was easier to frame the shot and know what you are getting through the view finder using the 2X.

Yes, I use it with a Canon 100-400 and yes, you do have to manually focus the lens. I do not see this as a major problem.

The Canon EF 2X II Extender Telephoto Accessory works exactly as described by Canon!

This is a must to get closer to your subject. I haven't noticed any loss of picture quality. Very slight if any.
Fantastic for the money. Amazing results.2010-01-25
I might have taken the best shot in my life with the help of the 2x extender. I was able to get a close-up eagle in action. See images. It takes a little practice manually focusing, but it's something you can get used to. It would be better if the autofocus worked with more lenses. More specifically, the Canon 100-400 L Series (4.5-5.6) which I use. With this extender you can get you a great shot without spending $12,000 for an 800mm lens.

" For a list of all the ways technology has failed to improve the quality of life, please press three." - Alice Kahn This quote is certainly applicable to consumer electronics. From the very first commercially produced radios to the latest in high-definition television technology, the manner in which the components used to deliver our news, music, movies and entertainment are interconnected seems to have escaped logic. For both the newcomer and the old hand alike, connecting equipment in the most efficient and effective manner can be a painful chore. It is hoped this article will improve your background knowledge concerning potential A/V system connection schemes and where each is most appropriate.
