Specifications:
This tele extender can be used with fixed focal length lenses 135mm and longer (except the 135mm f/2.8 Softfocus lens), and the EF 70-200 f/2.8L, 70-200 f/2.8L IS, 70-200 f/4.0L, and 100-400 f/4.5-5.6L IS zoom lenses. Superb optically, it preserves the image quality of the lens it's mounted to and multiplies its focal length 1.4x. Effective aperture is reduced by one f-stop; autofocus is possible on any EOS camera when combined with a lens having an f/4 or faster maximum aperture. The new version II maintains the outstanding optics of the previous version, and adds enhanced weather- resistant construction, and improved anti-reflective surfaces in the barrel.

Pros:	Superb color
Cons:	Slight loss of sharpness

I bought mine from a local Canon dealer in Houston -- paid a higher price because I needed it immediately. When used with my 70-200mm f2.8 (non-IS) lens, it loses just a little bit of sharpness. Is it enough to bother me? NO! I use it all the time for baseball, football, lacrosse -- in other words, all of the outdoor sports I don't hesitate to put this thing on.

Pros:	Super optics. Easy to carry in your camera bag. Gives you the little extra tele-kick when needed.
Cons:	None

I bought this used on eBay and use it with my Canon 70-200mm F2.8 lens. Mine is the older version, however the optics are supurb. This is one f stop I don't mind trading for some tele power when needed.

Pros:	Optical quality, very good build.
Cons:	None.

Extremely happy with it. I use it often with my 70-200/4L on a Canon 10D body without affecting picture quality in any way. Good weather sealing.

Pros:	Compact, incredible optical quality, weather sealing gaskets
Cons:	None

This is a superb quality converter, giving barely any notable loss of image quality when attached to any of my "L" lenses other than the 300/2.8 where the image degraded notably.

Pros:	Almost no loss of quality
Cons:

This is a jewel. On a 300 f2.8 wide open (f4 effective) it's hard to tell any loss of quality.
On the 100-400f5.6, you have to manually focus, but quality is good.

On the 300 f2.8 with the 2x and the 1.4x results are still quite usable. I think this is 840mm at f8. Lots of length for very little weight.
