List of Sigma lenses compatible with Nikon D40

Remember it: The Nikon D40 does not include the usual autofocus motor (for obvious cost reasons) and leaves this bruden onto the lens itself. Of course, it means that some lenses are not fully usable with the D40. Some others have no problem with the small Nikon digital camera because they include the needed motor. Sigma published its own list of lenses compatible with the D40.
