I know the D70s kit lens is superior to the D50 kit lens. I wonder if the better D70s body and better lens will result in noticeably better photos than the D50 kit. The difference between the two is 500 bucks.

Any big reason(s) to recommend one over the other? Is the difference between the two really worth 500 dollars? I will use the camera for a variety of things, including available light, action photography, family, portait, landscape, and macro.

I did notice that the D7os felt a little more comfortable in my hand.

Thanks in advance.
