Wowsers. You beat everybody to it. But... no HR, how? :ph34r:

#3
Highly recommended, but no thumbs up?

#4
Just forgot the badge  Rolleyes

#5
Small typo on the first page - "plate" is plat.

 

Second page as well - extra space in front of a ? above teh MTF stuff.

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 Smile What's the focal length at 400mm at 10 feet?

Well done,

Also, I see that the Tamron 150-600 is also in your hands? Smile

Well, what can I ... say  :ph34r:

I think the 6D can only go down to f/5.6 so no - the AF won't work with the EF 1.4x.

It would work (to some degree) with a third-party converter that doesn't adjust the effective aperture.

The Tammy/Sigma are fine here - they are faking the effective aperture to avoid triggering the limiter in the camera.

 

About the effective focal length at shorter focus distances - no I didn't look into this. Isn't that a bit of a phantom pain in this case ? I can understand the discussion with a 90mm macro lens but with a 400mm zoom lens ?

The focal length shrinkage is pretty noticeable on the 70-300L. So when close focusing, you're not as close as you might hope to be as it were.

 

As another question for the 100-400 II: if you focus on something at one focal length, change to another focal length, does the focus remain at the same distance?

 

I haven't gone back and compared the I and II reviews here yet, but Lensrentals have also done a quick test at 400mm. In short, new one about same in centre, better off centre.
