I did a search, but could not find the answer readily. Perhaps the forum could help me. I have a Hasselblad Distagon 60mm lens begging to be used. Will it fit, via adapter, to my Pentax 645 without a problem? I understand that other Hasselblad lenses can be adapated, but was just concerned about the 60mm. Are there any issues I should be concerned about? I'm assuming I'll lose functionality for metering, but are there any other problems that I could find? Thanks in advance for any suggestions/recommendations.
