I also recently purchased an old Hasselblad Distagon 40mm f/4 with a working shutter (silver barrel). Unfortunately, the front element has some scratches and cleaning marks (the rest of the glass is crystal clear). Also, itís not a T* lens, so itíll be prone to glare without a hood (and sadly I donít have a hood).
Did you find a service that would clean/re-coat the lens, or did you manage to find someone/somewhere that sold a replacement for the front element?
I've been searching for a 40mm with a broken shutter, but haven't come across one yet.. I only paid $400 USD for this lens, and I'm on a very tight budget (med school..), so the cheapest alternative is the best one.
Thanks for your time!
