Nikon d40 wont autofocus
I am unable to switch from manual focus to auto focus on my nikon d40. In the menu when i try to switch from MF in the custom setting menu, it tell me, "this option is not available with current settings." i have an aspherical 28-90mm D lens. Help!

Your 28-90 AF-D lens can't autofocus with the D40, which requires AF-S lenses with a focus motor in the lens. Sigma lenses with "HSM" (HyperSonic Motor) in the name also have the focus motor.
