remember the Sigma APO 200-500mm F2.8/400-1000mm EX DG beasty lens a year or so ago and everyone feverishly anticipating its price expected to be between 5-7K USD? - well it's out on the market now to fit most mounts but dont expect to see too many around partly because of the camo paint job but mainly because of the 35,000 price tag :-)
