I didnt read the whole thread, so maybe it has been already said. Get the Canon x2 extender III for the 70-200L IS II f2.8. No need to buy the 100-400L anymore. If you need 400mm just use the extender.

Thanks p5freak!

Yes it has come up and it seems to be an alternative saving space, weight and money.

This is a short and much discussed Youtube review by Tony & Chelsea Northrup:

Many argue that the 2X TC degrades IQ to much, photos are soft, introduce CA and slows down the AF, others says it is great and works well.

Almost all agrees on that the 1.4X TC maintains IQ a lot better.

Two comparisons:

http://www.the-digital-picture.com/Reviews/MTF.aspx?Lens=687&FLI=2&API=0&LensComp=972&FLIComp=2&CT=AVG

How is AF speed, contrast and CA affected by the 2X TC III?

Would you bring 70-200L IS II f2.8 and a 2X TC III for a long safari and vacation in Africa? Or buy a 100-400f/4.5-5.6L IS II?
