Big, heavy and expensive

This amazing lens along with its little sister the 600 f/4.5 are the reasons I developed the EdMika EF-FD 0.75mm thickness glassless adapter for my own personal use and then later for others who wanted to do the same as me. There is a lot of info on this and the 600 lens on my flickr photostream in this set for anyone interested: http://www.flickr.com/photos/ontarian/sets/72157623884845990/
