I was given a Canon Eos Rebel XSi for Christmas (with the 18-55 IS kit lens) and i have been researching a zoom lens almost ever since (sports, plays, school program, etc.). I went so far as to buy a lens (55-250 IS) at Ritz and return it within the 10 day grace period. I recently tried my friends Sony H50 (sorry for the blasphemy). But at $330 and a 18-400ish zoom and a point and shoot, should I sell the XSi and downgrade? Is downgrading unheard of? What is the basic difference? Will my pictures of the kids be that much better? Crazy novice needs help!!!!!
