The lens came in silver and black editions and a matched macro lens was available.
The Product ID nomenclature is an unverified guess so far (thanks to Maxim from Sigmamuseum.com for that hint). According to its initial product announcement the lens came with a 17 elements in 13 groups formula, but the Lens Charts do list a 17 elements in 14 groups formula during 2000 until 2004, adding ID 786 as a piece of information in 2004, while ID 785 can be accepted as verified by Ebay listings.
