In case you missed it, the above video shows the autofocus speed difference between the Nano USM version of the EF-S 18-135mm f/3.5-5.6 IS and the STM version. The difference in this controlled test by Canon is definitely quite obvious.
What will be the first EF lens with Nano USM technology? I think we may find out at NAB in April.
