Just bought a Nikon D40 with an 18-55mm lens.
One word. Amazing.
The images are sharp and brilliant. Focusing is effortless. The weight and "feel" of the camera is perfect. Exposure is exactly right, every time.
The 6 mega pixel sensor is small by current camera standards, but I can make an 8x10 300 dpi photograph from one of these files.
Since the largest print I need for my current book is about 5x7 inches, the resolution of the D40 is perfect.
The difference between the D40 and my first film SLR, a Minolta SR1 is probably greater than the difference between the SR1 and the view camera that Matthew Brady used in the Civil War.
I have to learn still photography all over again.
