I am shooting a 50d right now, I am considering selling it and downgrading to maybe a 30d or 20d. The reason I got the 50d was the higher MP, because I was printing large landscapes. I will not be doing that anymore. My thoughts are sell the 50d, and with the difference in money, pick up a nice prime lens. I know a couple photographers locally are using older lower MP DSLR cameras for portraits.
