Thanks John. Sharpness with the 1.4X II and with the 1.4X III are pretty much identical. And this includes edge to edge sharpness. This is not the same as with the 2X II and the 2X III TCs.

The 1.4X III is supposed to have slightly improved weather sealing. In addition, there it is possible that the 1.4X III is better able to communicate with some of the newer lenses…. I will try to learn more about that and let everyone know via blog post.
