Will this work?
I can only find a direct answer on google re the markII extender working.

I assume there will be no difference in compatibility, but does anyone know for sure please?

Optically both the Mk I and Mk II 1.4X extenders should be the same, there was no optical improvements to the 1.4X MkII, only to the 2X Mk II extender.

Even the 2x MkI to MkII difference is subjective, changing in priority from edge to centre (see luminous landscapes for a test). As the 1.4x only gives a moderate depletion in quality, the 70-200 is so damn sharp in the first place, and the resulting f5.6 aperture still allows full AF on even non-pro bodies, I would be more than happy to use this combo. The results should still be excellent.

Well it dropped through the letterbox this morning (not literally!) so I shall see for myself soon. Thanks for all the feedback. I didn't expect it to allow IS, but it does, so I am happy so far. No doubt I'll play with it, testing it against the lens alone when I get the chance.
