I looked into the CL when it was introduced in the 70's but kept my IIIG. The CL can only use a limited range of M lens, at the time I really needed the 135MM, I think it may use the old mercury batteries. Some people thought the Minoltia (sp?) CL body was a better buy. I agree with Hans, unless you are a collector, I would look into the Bessa or Konica M mount.
