Hi all, I am planning to buy a DSLR, and I am considering either the Canon or the Nikon brand. 300D, D20 from Canon or D70 from Nikon. I have some Canon lenses, so going into D70 will also mean some new lenses, which means I need some reviews, and insights about both Nikon and Sigma. I do not plan to go into high end. Can anybody point me to some websites that review lenses? Also I would like to hear from anybody that have hands-on experience with those brands. Thanks for answers, Veli Izzet
