Sigma 105mm 2.8 macro DG EX OS HSM for Canon EF.
Very good condition macro lens. I used it with my GFX100S to scan my negatives, it worked amazingly. Very sharp, detailed. Covers fine the small MF (44x33) like the GFX system. I switched to a different lens, which is why I sell this one now :)
Good condition and no issue detected while I used it.
