I need some advice. Based on my research, I'm torn 50/50 between which to purchase. I'm getting a Rebel XT in the next month or so. My main goal (reason for purchase) is to get better pictures of our 2 month old son while he's growing up. I also plan to take some wildlife and zoo photos next year. So should I buy the camera with the lens kit or get Canon Normal EF 50mm f/1.8 II Autofocus Lens instead? If I get the non-zoom 50mm, do you think I'll regret not having the zoom? I also plan to do some macro stuff. Will that 50mm work well for macro shots or will I need a different lens. I've already decided that I'm going to get the Sigma Telephoto 70-300mm f4-5.6 DG macro lens for my nature and zoom shots. Made this decision 10 minutes ago after seeing that all those doenoe were used with that lens. So, please help me decide what I should do regarding the 50mm f1.8 and kit lens.
