This huge lens was introduced at PMA 2008. It is meant for conventional photography. But even if I could afford it--its a whopping $25G before tax and shipping--you wouldn't catch me carrying it around--it weighs 35 lbs--in downtown Boston. I could be taken down by Boston Police for suspicious behavior.
Had this lens been around last year, Eliot Spitzer would have been caught doing the nasty earlier.
Ken Rockwell has a note on this lens in his website.
