How do you folks find the difference in AF speed? Would the 55-250 focus faster thanks to its STM motor (despite the lack of L designation)? I have a 7D and I'm looking to get a decent telephoto for sports. I'd appreciate the wider F4 aperture at the long end but it's only a one stop advantage (and maybe I should spend more for a 3rd party f2.8).

Canon EF 70-200mm f/4l Focus faster and more accurate and does not focus hunt as  the ef-s 55-250 STM does sometimes when zoomed in.
