Well if by the word sports , you are asking if the camera is good for action shots ..
I would say , that yes it does some good work with the IS disabled .
And with some easy tricks ,you can by pass the focus lag ..
One tip for you is to shoot things that they are heading to you .
I have find out that its hard to try to follow with the camera one moving subject .
Specially if you do not using manual modes .
In this area is not what the camera could do , but how well the photographer will adjust the camera in order to get the best of it .
I tried hard when i got my camera ,to learn and improve my self ,it took me 7 months and 1500 testing shots .
Plus reading the full users manual ,plus one book that i got ,that it is specially written for this camera .
Here some samples for you .. (Not my work ,but they are taken with C2100)
