A: FotodioX Pro Lens Mount Adapter with Generation v10 Focus Confirmation Chip for Nikon F-Mount Lens to Canon EF or EF-S Mount Camera has a focus confirmation chip that when you have successfully focused the lens manually and you press the shutter button half way the focus point will light up and will also beep.
