Hi Again Dave, There will always be some degradation, about 14% or so with a 1.4X TC. But the top of the line lenses are so, so sharp that it is easy to produce professionally sharp images with all three TCs with perfect technique. I am betting that the new 80-400 is money in the bank. If you see any bad reviews from the internet experts make sure to ask them if they ever used one….

I was confused as I thought that you went from the 200-400 to the new 80-400. My bad.

I prefer the 1.4X and saw no noticeable degradation in IQ. I also use primarily DX bodies so I would get more reach but have added a D600 to the mix. I think you will find this new Canon version to be one you will bring along quite often. I have been trying get my hands on all legitimate reviews for the Nikon 80-400 to see if it is worth parting with the 200-400. Thanks for the questions and enjoy!
