IS and Sports question

Yep, the flash config would be neat, until my son came home and kicked my a#@ for making him miss the shot! I do see some using flash at the games, but I know it does bother some (at least my son) so I try not to use flash.


Thanks for the input. So if I'm keeping my shutter speed at say 200+, do I need to worry as much about IS?

The general rule is 1/(effective focal length). Let's say you're using a 100mm lens on a camera body with an APS-C (1.6x) sized sensor. You multiply the focal length by the sensor multiplier, giving you an effective focal length of 160mm. That would mean you typically need 1/160 second or faster shutter speed to prevent blur from camera movement.

I had seen that calculation before, but thought it was more for the motion of the subject, not the camera. Thanks.
