To be true to the proportions, it might be more accurate to say that the camera and the photgrapher is mounted on the lens, instead of the other way around..LoL.
Too bad they didn't make one for the DX format, which would make the lens not a 1700mm but a 2500+mm.
...I shudder at the though of bringing enough batteries to run this beast. I don't see any zoom-ring around it (duh!) so it must be electrically operated.
...better get an Opetaka grip for that suckah! What does it use? 250 D40 batteries?
...and somehow I don't think that the built-in fill flash will amount to much and even if it did, there would be some lens shadow to consider..lol!!
I could see Nikon build the "SB10000" commander-flash - it can alternate as search light for flak-guns.
