BANG-ON focus dude! Good shot too! I love the Run, Lola Run! reference! That was quite a movie.
So, what focus sysyem settings were you using for this shot? In the past, I have found that for subjects coming directly toward the camera like this, which is a very common scenario in track and field action photography, a multi-point AF approach and an AF-S lens have been the best solution for me, shooting Nikon.
Are you using the 4-way controller, AKA the "thumb BUTTON" on the back,to manually select the initial area for the camera to focus on, and then allowing the light metering/focusing COLOR-AWARE evaluation of that subject's reflectivity and R-G-B color makeup to keep the focus on that same-colored object as it moves across the frame?
What are you doing now that you were not initially doing? Can you pull this shot into an EXIF reader, and come up with some important info on AF mode, AF pattern focusing points used, etc???
