I began wondering about this product when I purchased the 70-200 f2.8. I absolutely love that lens. But I found that, occasionally, I might like to get a long distance shot, so thats where this product steps in. Originally, I had considered buying the 100-400, but I decided against it, since I found out that the 70-200 f2.8 is rated much higher than the 100-400 and since the addition of the 2x extender Mk iii to the 70-200 f2.8 Mk ii wont compromise significantly neither image quality, nor autofocus. Now, I have to say that they were totally right. I couldnt be more satisfied with this product. It pairs extremely well with my 70-200 f2.8 Mkii. Images are beautiful and sharp and autofocus isnt noticeably affected. Highly recommended.

I have a Canon 70-200 2.8 II and I picked this up so I could double my range while still enjoying image stabilization. It works perfectly in combination with that lens and now I have the best of both worlds.

I really had my doubts about this extender, now I don’t know how I lived without it. My 70-200mm suddenly becomes a 400mm and I’m not really giving up anything other than going from f2.8 to f5.6 but that easily compensated with speed or ISO. I’m heading out in the morning to the local zoo, can’t wait. A very inexpensive way to own a 400mm lens. Buy this you’ll love it.

This is exactly what the reviews said it would be. This is a great bargain if you have an L rated telephoto. Check to make sure your telephoto qualifies for use on this product. I use it with my 70-200mm L IS lens and it produces very good images. Unlike previous tele extenders, this one produces very good images. I have a few hanging on my wall. My images are tack sharp showing very good detail as long as you dont have to do too much cropping. Cropping does compress but the clarity is retained. I highly recommend.

I own the Canon EF 500mm f/4L IS Lens. Not the version II. The original lens. I also own the 1.4x teleconverter version 1 also. I bought this for bird photography because the 1.4x was not quite close enough to suit me on the smaller birds. My blind is set up at a fixed distance so its pretty predictable how much telephoto power I will need. I am shooting with at Canon 7D Mark II. The effective focal length with this converter on a 1.6 crop camera is 1600mm. Very, very nice. Unlike other reviewers I found this teleconverter to be the equal of the 1.4x (at least version 1). I cant imagine it being much sharper. Please see the full frame dove shot and the 1to1 crop. You can see the full frame uncropped full resolution image at flickr.com/photos/davidpitts/18102024249/sizes/l If you need the reach and you have a Canon long prime lens, Im not sure how you can go wrong. I should add here that I spent considerable time working with Canons AF Microadjust feature for this combination of 2x converter and lens. It made a significant difference in sharpness. If you have this feature on your camera you should do this for every lens.
