Help! Agonising for ages over 1st DSLR between Canon 400d and Nikon D80, almost decided on Canon due to budget (less pricey plus has the software.) But not sure how much the lack of spot metering is going to affect my photography in the future - I would quite like to do try my hand at portraits. Incidentally, any comments on my choice of lense - Sigma f2.8 24-70?
