I sent my Hasselblad 500C/M, 80mm Planar lens, and an A12 back to David Odess for a CLA in 2018. The camera has worked like new ever since. I just learned that Mr. Odess passed away recently (Aug. 2023). This is sad for the obvious reasons, but it's also sad because a lifetime of knowledge and craft around maintaining the Hasselblad V system has been lost.
