Quote:Klaus, this was fast.
Will this lens work/af with 1.4x extenders on a 6D?
Talking about extenders, you should add 1.4x resolution results to the review. Many will be deciding between this and tamron/sigma 150-600s and it will help.
Also I will appreciate the close focus results as the MFD is good.
And lastly, focus breathing What's the focal length at 400mm at 10 feet?
When you use a Kenko TC, the center AF point probably will still work ok in good light.
The focus breathing, I can't answer what it is like at 10 feet (about 3 meters).
I just figured out what it is like at MFD (comparable to what the 70-200mm's from Canon have FOV wise):
