This is the Canon RF mount, RF 100mm F2.8 L MACRO IS USM lens. It has been used very little and stored in a dry cabinet. In my subjective opinion, the lens has no dust, mold, or fogging, and there are no scratches, so I believe the condition is good. There is a slight scuff on the included lens hood that can be seen depending on the light, but I believe this is from storage. It comes with front and rear lens caps, a lens hood, a filter, and a storage bag. Due to the high price of this item, no claims or returns are accepted. I have borrowed the "EF" category because there was no "RF" category.
