Our reader David (Thanks!) made this very interesting AF speed comparison between the [shoplink 8452]NEX-5n[/shoplink] 1.01 and 1.00 firmware. He tested the speed on both 18-55mm and 16mm lenses and as you can see the speed improvement is significant!
The firmware is available here at Sony UK (or select another country). The NEX-5n here at [shopcountry 8452].
