I have a used soundproof blimp to be used with Contax 645 with film back or digital back. the lens tube will fit the 45mm, 80mm, 140mm for sure, and probably some of the others. comes with flags. This was primarily used for shooting on set film stills or on set stills in conjunction with a broadcast shoot. You could probably use it as a water resistant case as well, but I never did. I am in california. Price is $650. Might be interested in trades.......
