Would a nikkor 24mm prime Af lens still auto focus on a nikon d40?

Is the 24 mm an AF-S lens?

Of not you will have to manually focus it using the electronic rangefinder in the cameras viewfinder.

You do know I hope that a 24 mm lens is not that great a wide angle lens when used on your camera, it is closer to a 35 mm lens on a full frame or 35 mm camera

If its an AF-S model it will auto focus on your D40. If its an AF model you'll have to manually focus it.
