Hi. I will be going to a friend's sister birthday party. We will be salsa dancing and I have a Canon Rebel XTi with a Quantaray 28-200mm 1:38-5.6 MACRO Aspherical XR (1F) lens. What settings do I need to change my camera to so that I can capture images of two people dancing without having them come out distorted? Thank you for your help.
