I saw the public debut of this beast at PMA a couple years ago...
Trust me when I tell you that pictures don't do it justice. Yeah it's big but the thing has enormous mass as well. Consider what diameter of front element you need for 800mm @ f/2.8!
I think the tactical green is a nice touch but if anyone ever drags one of those out near an airbase, they're probably going to find themselves face down in the dirt ASAP.
I think a 800 f/4 will already have bigger diameter than a 500mm 2.8. Can't imagine how gigantic the 2.8 version could be.....
