thats cheap, they have however dropped a lot in price since I go mine, I thin k I paid about ?800 to 1K now you can pick them up for about ?5 1/2 hundred, these are the APO EX (Sigmas version of DX)of course and not DX very similar inoperation though and they work fully on Nikon digitals of course. Because of its huge size I usually have it slung round my neck at weddings, not because I use it in these situations, but because its very good for the old street cred and impressess the brides maids, (wow thats a bigh un, yeah babe, thats what all the girls say), plus people think you know what you`re doing, when really i don`t have a clue.
