Hello, I'm looking to purchase a dSLR for the family. My research has led me to prefer the D50 but my brother is leaning towards the Rebel. I have done more Nikon research than Canon so I may just be biased. The camera would be used for sports (Running- cross country and track, skiing- rails and jump action shots), and the usual vacation and family photos. Can I get some pros and cons for both cameras and which you prefer? Thanks!
