Good point, Keith.Everyone has their own favorite style. Speaking only for myself,I can see unacceptable perspective warpingusinga 50mm lens. If the purpose isdo a flatteringportrait of someone, I wouldn't go less than 70mm on a full-frame.Another advantage ofgoing long in a public situation is that the politician needs to be the center of attention. If you're using a short lens, you have to get too close to get the shot. In other words,you become too intrusive. It's not your place to be part of the action--you're just there to documentit. When shooting at a public venue, go long-ish and stay out of the way. If there are other photographers on scene, they'll thank you fornot blockingtheir shots.
