Re: Canon Extenders II vs III

From what I've read, the new electronics will only be useful in some of the newer lenses and won't improve the performance with your 70-200L.

As for the improved optics, most reviewers have indicated that the difference in IQ between the 1.4x II and III is pretty slight, while the difference between the 2x II and III is more noticeable.

So, if you're only considering a 1.4x TC, and don't plan to buy any of the newer telezooms, I'd go with the II. If you want a 2x TC, then the III may be the better choice.
