Having updated mine I can say that:
-MF seems a little more responsive. Its also easier to notice when in and out of focus, or ir that just wishful thinking on my behalf? no, after further playing around I can say the MF is now more useful. . YES, just had a little mess about, it certainly has improved.
-AF seems faster (I say 'seems', as io dont carry a stopwatch with me.
-AF distance has improved, but only in EVF it would seem. Camera wouldn't focus on a subject about 40cm away in OVF but would do in EVF. Still, not a great issue, as I'd always use EVf when focusing on something close. No need for Macro now, it would seem.
Yes a worthy update indeed. All those who have decided against updating to 1.11, give it a try. I think Fuji have given a flase impression of the update making quite a fw people think it's pretty much insignificant.
