So after doing some research on the lens this is what I found. It will work with Nikons D Series but will not auto focus. I have a D5200 and it worked great but no AF. The mount is an Cannon EF so it should AF with the Cannons. I will include the link below for you to follow up with. Lens caps are missing. Smooth operation and took some great photos. No damage to the barrel.
