18-135 is a very good choice, i would be more comfortable with something starting 15 or 16mm on APS-C however in Sony world that's what is available.
Another option to consider if your main target is video is Sony 18-105f4
However if it's sold as a kit, you won't be disappointed by 18-135, but by all means stay away from 16-50 the collapsible, I gave it all the chances, repaired twice and I bought it not once or twice but four times, and each time it was the same, collapasible mechanism failure,too expensive repairs, better buy another one.
