I just purchased the Kenko 2.0X PRO 300 Teleconverter DGX for my D700 Nikon and found that it works on my old Nikon lenses very well (50mm 1.8 and the 70-200 2.8). On my other Nikon and Sigma lenses, I encountered so many problems with auto-focus. I didn't know of these compatibility issues when I bought the lens; however when it is compatible, the operation is really good and fast. I have yet to see the sharpness results, but I don't expect it to be as good as the original lens I'm fitting it on. Glad to see this video though!
Kenko website is terrible and is way behind the times,,, when checking compatability on the site they dont even list newer cameras such as Nikon D850 nor some lens such as 200-500 F5.6 nikkor... So now I will buy a diferent brand...... Terrible Kenko

It would be nice if you would post a link (or links) in the video description.
