I've had my D40x for over a month and took some great shots with it. But as I see the prices and reviews for some of the AF-S lenses I am becoming more aware of the D40x's limitations. I already have a few lenses in my sig that will not auto focus with the D40x, I was looking into the D50. I was thinking that I should sell my D40x and buy a D50 body and use the rest of the money on glass. My only worry is that the D40x has a 10.2 mp sensor as where the D50 only has a 6.1 mp sensor. Is this that limiting? If so, do you think I should just sell my D40x, and save up for a D80? Thanks for your replies.
