And's probably half the size. So many lens designs are a stretch because of marketing demands from the marketing department. (where else?) An F4 lens becomes an F 2.8 lens and should have stayed an F4 lens. Its now bigger and flarier and cost more and not that great at f2.8. I'd love the 4.5 I doubt this was the case though with the Elmarit ASPH. Mark William Rabiner rabinergroup.com
