HC100 2.2 AF

[martinnz]

Just wondering if anyone has this before. My 100mm will not AF. The motor makes small movements only. Have cleaned contacts 3 times with isopropyl. I get no error messages on the H3D39. My 80 and 28mm work fine. Only around 2000 actuations on the 100 so a bit surprised if something is broken. Manual is fine. Any way I can check resistance on the lens  contacts to see the problem. Thanks Martin

Checking resistance on the pins won't help you because they are data connections, not analog. I can't offer any more advice, you have already done the obvious things.

Mine had the same problem had to send back to Sweden to be repaired. Have encounter 3 other units with the same problem

I had a similar problem with a brand new 35-90mm. Symptom is loud whirring sound when AF and AF does not lock. Sent back to Hasselblad. Outcome was AF module replacement.
