OK. This is a long shot, but there's plenty of photo knowledgeable Americans on this board so I though I'd give it a punt. I've got my eye on a Nikon AF 80-400mm f4.5/5.6 ED VR lens, which will cost me about £1100 However, I'm off to Las Vegas for a wee holiday in a few days and the US price for that lens works out to be the equivalent of only about £800, which is quite a saving. Does anybody know of a good photo store in Las Vegas where I might get this lens? Thanks.
