I'm currently on 1.5 having not got round to updating with the last (1.6) update.

Having had a quick look at the release notes a couple of things caught my eye.

The password thing in 1.6. How does it work?

The improved AF tracking on 70-200 f/2.8 Z. Is it a noticeable improvement?

The ability to pick 5 GHz or 2.4 GHz band. Is there a substantial / noticeable change in transfer speeds when on 5 GHz?

Are there any other major improvements that I'm missing jumpring from 1.5 to 1.7 othere than the usual list of bug and system stability fixes they mention.

TIA
