Pros: Double the focal length, improved AF performance and quality compare to 2x MK II TC, good quality even in low light.

Cons: Canon make very bad move not allowing to stitch the 1,4x and 2x TC, which was possible with the Mark II edition, loosing some light and AF performance

Opinion: I use it almost full time with my EF 300mm f2.8L IS USM lens and I am really happy with the results. I recommend upgrade from MK II version of the 2x TC. I guess is much better with the MK II lens, but I am still satisfied with it now. Had to agree the quality is much better with this two on a FF body like 5D MK III, but I am expecting that the 7D MK II will make this lens and extender a hot couple even on crop sensor.

Pros: -Surprising high image quality for a 2X extender -High build quality, water resistant.

Cons: -autofocus with the 2x extender is disabled on F5.6 lenses such as the 400mm 5.6L, though you can actually autofocus through live view mode using contrast detection. -strong purple fringing at times when subject is against the sky. You can work around this be turning the saturation down on the purple color though. -soft at the wide open aperature. Stop down one click (one third of a stop) and most of the softness goes away.

Opinion: I have a Canon 5D Mark II. Using the 2x extender III on the Canon 400mm 5.6L is the cheapest way to get to 800mm using Canon L series lenses. The 400mm lens can be bought refurbished for 1000$ and the extender is around 450$ on sale. 1450$ for 800mm is very good value. Checkout my eagle pictures on my profile to see the image quality. As i mentioned, I recommend stopping down one third of a stop to get more sharpness. For example, if you are using the 2x extender on a 2.8 lens, the aperature will now be F5.6. Stop down to F6.3 for sharper results. I usually shoot at F13 on my 400mm 5.6 lens. UPDATE FEB 2013: I have been now using the 2x extender with the 135mm F2 and the 24-105mm. Yes you can used the 2x extender with the 24-105mm if you place extension tubes in between. see my macro photo of the wedding ring.

Pros: Well built and tropicalized

Cons: Nobody

Opinion: I use it with the Canon 70-200 2.8 IS II, the performance I find, at full aperture F5.6 400mm, higher than the "pompone" 100-400, sharp, more contrasted and AF slightly faster than the old 100-400. No AC on my 1DX, very high level performance, paid the necessary to have a level yield and, above all, no mechanical game

Pros: Tropicalization, construction, loss of sharpness not particularly marked

Cons: A few qualitative decay at the edges, purple fringing on some machines.

Opinion: I have had it for about 5 years and have been able to test it extensively. It's almost a fixed pair with 100-400 II. I find it to be a great extender, both as a construction and as an optical quality. Of course, some compromises must be accepted in terms of detail, but, especially in the middle of the frame, quality remains entirely acceptable, not to say very good. On canon 70D the pairing featured purple fringing around certain subjects, on canon R5 I no longer know this problem. Autofocus also works safely on mirrorless. It worked decently even on sony adapted with metabones, now on R5 goes that it's a splinter. On reflex, on the other hand, once the lens was mounted it became practically only manual focus.

Pros: quality, yield, weight, clutter.

Cons: nobody .... price?

Opinion: taken used ... but equal to the new ... just recently, I took it to match it to 70/200 2,8 is II, I did not notice any differneze rendering or autofocus details when using the 70/200 alone or in pairs. I bought it because I had the old pompone 100/400 but, despite being satisfied, I had to go around with 70/200 and 100/400 to cover the focals up to 400 (hence two beautiful heavy targets + the rest of the etc.), with the 2x 2x extender I solved the problem, weighs a bit, is not very compact and with the 70/200 2,8 series 2 it has a great output with both 5dmk3 and 1dmk3.
