Quote: gavincato, may I ask you a further question? While searing for this lens on ebay, I see lenses of various serial numbers. Is it better to go with the latest serial number or it doesn't really matter?
really not sure sorry. my knowledge of hasselblad gear isn't that great. I seem to remember something vaguely about there being a couple of generations of this lens - I know I have the last generation of this lens, I paid a fortune for mine as it was basically mint and looked brand new - it had hardly been used. I'm never letting it go

If you were interested, get onto some other medium format forums (such as luminous landscape, getdpi) the guys there are encyclopedias on other systems.
