i have been given a lens that fits a hasselblad camera. i know very little about it. the body says Hasselblad and also has "super wide C" written on it. the lens says Carl Zeiss , biogon, 1:4,5. f=38mm. also the number Nr 2766947. any help with its usefulness and value, or lack thereof, would be appreciated. i would like to sell it but it has been in storage for some time and is quite dusty and perhaps out of date for todays photography. thanks in advance for any information.....
