Well i finally got home and opened the package immediately. The CL and Summicron arrived safely! The first thing I did was to mount the M-Rokkor 40mm lens I already had onto the CL and mount the Summicron 50 version 3, onto my M3. I put a strap on the CL's side strap loops and went for a walk into town. I took a few shots at the train station, but I immediately realized that I didn't like the side strap loops, not on that side anyway. I like to wrap the neckstrap around my right wrist, and it just didn't work with the strap on the left side of the camera. I'm going to have to use a wrist strap attached to the tripod socket at the bottom of the camera.
Anyway, I'm satisfied with the gear trade Mike from Tokyo and I worked out, and am happy to recommend Mike as a "ggod guy". Thanks, Mike!
