I bought a Nikon SB600 Speedlight. It is a detachable flash for the top of my camera. I love it so far. It works great with my Nikon D-50. The flash syncs with the camera. I am lazy and like to shoot in auto. It is making those pictures a lot better. It is also good because I can adjust how much light is being flashed, even in auto. It is a great photo toy. Anyone who likes to photograph people with a digital SLR should get one.
