Here’s a good example of filming tennis at night.  This match started out in the daytime and ended up at night under some pretty regular court lighting.

The MUVI K-1 did a pretty decent job of capturing the action under the lights.  The newer KX-1 and your smartphone will actually do a better job!

Camcorder mounted on 10′  fence with the QM-1 Camera Mount.  Setback = 21′
