I have not used my EL/M body for some considerable time and recently decided to bring it into service. I puchased a new battery (ouch!) and gave it a full charge in the camera but when I tried the release I got nothing but a soft click from within the body. To make matters worse I attached a lens which although has located in the mount will not fully lock into place nor will it release from the body. I suspect that the body must have been mid cycle before the battery was charged but I am puzzled as to why it did not complete the cycle when the lock lever was moved to '0' position.
Can anyone advise please?
