Canon lens with excellent optics. Always used with UV filter. Includes both caps (front cap is 3rd party) and Canon case. I've had fun with this lens and taken some of my favorite photos with it, but switching to mirrorless. I have a long history of buying and selling camera gear on another platform you've heard of, but am tired of their fees. You can check my seller ratings there by clicking Advanced Search and then selecting "By seller" and looking for sandhilldesign.
