This is a fairly rare 100mm macro lens from Canon. It is great for macro and is also excellent for tight head shots, since you never run out of focus when you get close.
It is does 1:2 magnification without accessories.
The lens is in excellent with light wear and works perfectly. There is a small spot with some slight coating wear and a few light cleaning marks on the front element, but neither will affect your image quality. Otherwise the glass is clean and scratch-free and everything works perfectly.
The lens caps are included.
