Still waiting to see how much better the AF is ......
I'd like to help but I suspect that most who now have a MkII have disposed of their MkI - so side-by-side tests will be few

My view is that it is improved, it seems quicker and appears to "lock on" accurately more often - but I couldn't say it is light years better.

We'll see but I am going to take a wild guess: not really significantly better.

It will depend on your definition of significant.
With the MKI I had changed the AF method to centre spot (as I have used with all previous DSLRs) as I never found the multi AF consistent or overly accurate, on the MKII I am happily shooting without having to change from the default. To me this is significant progress, but I'm not shooting Birds, Aircraft, Racing Cars, etc.

The multi AF method breaks down when one tries to take a telephoto shot of a bird perched in a tree. The multi point AF system has no idea what to focus on but with the centre spot method it has no choice.

In a review somewhere I read that the battery demand is higher with the Mk II so the number of shots will be less.
Follow the link in my first post.
