Actually it has so much glass, that you will have a hard time counting.
You can pop on sonys own converter and use every Sony and Minolta A-Mount lens that is available on the market used or new.
without losing ANY functionality...
(framerate will be a bit slower than with native FE-lenses but it still kicks 455)
or you can use that new Sigma adapter so you can use every Canon-EF glass on that sneaky A9...
all that plus the native offerings for the E-mount add up to a multitude of options for sports photographers.
