This Ricoh 500 was an early acquisition some years ago when I first got interested in old film cameras. It bore a resemblance to the mid-century Nikon and Contax rangefinders, and it also had some interesting design innovations of its own. Dribbling a little lighter fluid into the shutter got it working well. The pictures from it were a disappointment, however; they were all lacking in sharpness.
I found some reports of similar experiences to mine with the camera, and it got parked on a shelf for the next five or six years.
Recently, I came across some rather nice images that others had made with the same camera. I decided it was time to revisit the Ricoh. This time I removed the lens retaining ring and screwed out the front lens group so I could get access to the shutter blades to clean them. More importantly, I correctly reset the infinity focus using the collimation process described by Mike Elek. The results speak for themselves.
