Hi, I am being offered a Hasselblad Distagon 50 mm lens, C version. The serial number is 3879126. I wonder how old this lens may be. I tried a webpage from a Historical Hasselblad Society, but the website wasn't working and I didn't get a production year. The other question I have, I wonder how good the performance of such a lens may be on both a Hasselblad body, as well as on a dSLR? Last, but not least, what would be an appropiate price for such a lens. Please feel free to post a price in your currency. Thank you in advance, kind regards, igmolinav : ) !!!
