This is a must for any photo kit, BUT you have to remember, the AF does not work with lenses slower than f/2.8 ! ! !

Pros: Superior build quality, Fast auto-focus, reasonbly sharp, improved contrast over old ef 2x
Unlike the EF 1.4X II the EF 2X II shows noticable improvement in image quality and in particular contrast over the old Ef 2X extenders. I have used it with various EF 70-200 2.8L IS USM, EF 300 4L IS USM, EF 300 2.8L USM, EF 300 2.8L IS USM, EF 400 2.8L IS USM lenses mounted on EOS 1D, EOS 1Ds and EOS 1Ds mkII bodies. The difference is subtle but noticable and IMO worth the upgrade cost given the less than perfect optical performance of the original EF 2X extenders. I can say that if you are needing to gain this much more focal length you are much better off using a longer lens. But if you are at the limit of your bag or kit this one little extender can sometimes put meat on the table with careful use.

Pros: Super-sharp images, Superior build quality, Fast auto-focus
I have had the 1.4x and the 2x extenders for a while now and they are a must for every photo kit. They both are an excellent addition to the 70-200 f/2.8L IS. Autofocus is great on both my MkIIn and the 40D. They are great for plane-spotting and the zoo. They also do a great job with sports.

Pros: Super-sharp images, Superior build quality, Fast auto-focus
I use this extender with the 70-200 IS lens for a long time and it is better than i thought! It's very sharp from corner to corner and the autofocus does not slow in comparison with the 70-200 IS alone. Excellent form every aspect!!!
