You are bidding on a 14mm f2.8 Sigma HSM Aspherical lens in CANON mount - number 2003861 This lens has seen little use. I bought it to give me a wide-angle capability with the D60 and 1D cameras. Once I moved to the 1Ds Mk2, it has not been used It is optically perfect and gives a very sharp image The lens body itself is just about in perfect condition with the black finish rubbed-off in a couple of places on the very edge of the built-in hood and the lens cap is a bit scuffed The padded pouch has never been used and is as new and the box is the same It has all the information leaflets and even has the original plastic bag! (but the little pack of silica gel is missing)
