Good Lenses for videography
Are the USM lenses like say the 15-85mm that much easier to focus manually during video?
Only been using the 24-105 and 70-200 f/2.8 and while you can certainly do manual focus with them in video it's not anywhere near perfect unless you practice a lot I guess! Zoom and focus on SLR lenses are not ideal for video IMO
(But can of course be used with very good results, it's just not perfect)
