If you must know I have already posted this on several sites, I just figured that maybe a photographer that frequents this site might be interested, but since your so quick to assume I bet you haven't even taken that into consideration.
dude people are harsh this lens is actually pretty nice. By no means a stellar surf lens but could do a lot with it here seeing as how we have some close breaks. Slap a teleconverter on that thing and it would do just fine. And a 180mm fixed 2.8 FROM NIKON is no cheap lens. 500 bucks sounds like a good asking price. Even the sigmas at 3.5 start at $700 brand new
$530 doesn't sound ridiculous if it's in good shape, but I have to agree with the others that a 180mm prime is short for surf photography. That's a nice lens, though, and the right buyer could make some nice work with it.
sorry there john didnt mean to come across harsh. have you tryed nikonian dot org? thats a great site they have a huge buy, sell and trade thread.
