So me and the wife are looking at buying the Nikon D40. To save the money she spends getting the kids pictures taken. Well I will be honest and say I know nothing about DLSR. I have had a few point and shoot 8mp sony's. So is the D40 a good camera I mean is it easy to use? Is the lens that comes with it good? Why do I need different lens's? Is there any thing else I really need that doesn't come with this kit? Is there any thing else I should know? And one last thing how is this price, I have a addtional 10% off.
