Lens is in fantastic condition.

And takes sharp high quality images. Glass is free of any dusts  or mould and is pristine. If pedantic there is about 1 mm mark on the glass hard to pick up on camera but i believe if you squint you can see in the photos. It has not affect tge quality of images and i have attached sample to see thr beauty of the images it takes.

Canon Macro Lens 100mm 2.8 USM.
