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?

Well done,

Nde

 

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):

Hi, please PLEASE repeat the tests on a crop body, ideally comparing it to the version 1 (which unfortunately means you'd have to test it again on the 15MP testing body).  There are a lot of birders looking at the 7D II/100-400 II combo right now, so performance on pixel-dense sensors is very important, even if those sensors are small.  

 

In short, please compare this lens to others on a crop body.  Thanks for the quick review!

I have just uploaded some sample images into the review.

At some stage I may do this but not on the short term.

First I will have to see how it goes with the Tamron 150-600mm on full format.

Very Stupid Question: do somebody figure out how it performs on a Sony E-Mount via adapters? Also for what concerns focusing speed.
