Some people have found that the 2.8 70-200 with tele extenders give results similar to the 100-400 mkII (which I own and really like). Just thought I'd add another consideration to your process.

Thanks flbrit!

I found this very short review https://youtu.be/n9zWpihW8IE by Tony Northrup some time ago and the thought of having the best short tele and adding a 2X III extender only when really needing 400mm is quite tempting.Saving a whole lot of space, weight and money.

Some comments below the youtube review of this combo tells that it work very well for casual use others says it produces soft images, introduces CA and AF becomes really slow only working for slow to stationary targets in good light. Forget Eagles i flight but OK for ducks and lager animals?

Q1 - Even if resolution holds up and is still OK at 400mm, how does it really compare to the new 100-400 II or my old (sold) 400/5.6L prime?

Q2 - I am sure AF speed, contrast, CA and general IQ is also degraded, question is by how much?

Q3 - Can you post or point me to examples of this combo perhaps on Flicker?

Thanks for reminding me of this possibility!
