1.4 won't focus faster, it will just be able to use a faster shutter speed (assuming you use a wider aperture). You need to adjust your focus mode and/or shutter release mode.
For starters, are you shooting f8 or wider?
I am shooting at f4.0 and my shutter speed is approximately 1/500 of a second. Am shooting in Aperture Priority.
