I agree with those who say the CL is a little louder than a typical M or Barnack, but still quieter than most other cameras I've owned or handled. The CL is a wonderful little camera that, though I often dream of selling to put toward an M6, I can't seem to part with. It is light, relatively sturdy, and I love the metering on it. It used to give me crappy low light readings until I sent it to DAG for a CLA last summer, got a Zhou half case for it, and now it's a truly fantastic little camera that I am happy to own. There are a lot of banged up ones out there, but a good-working CL is a gem, in my opinion.
