Like many people here, I have used the Konica Auto S2, which is widely written about and which deservedly is labeled as a bargain quality camera. I was so impressed with the S2 and the S that I looked for additonal Konica RF cameras.
One day, I bought a Konica, which is the first of the Konica RF series of cameras. It is also referred to as Konica I. There are several websites on these older Konica RF cameras, so I won't waste your time on technical issues here. The Konica I has a sharp lens Hexar 50mm/3.5 lens. It seems that it was also sold with a 50mm/2.8 Hexanon lens. The 50mm is collapsible. The shutter speeds range from B,1, to 500.
One quirk with this model is the film advance. You must push a small button located closeto the VF each time you want to advance the film a frame by rotating a knob.
Quality of craftmanship is first class. This is a small, but heavy camera made out of metal. It gives me fully manual control of exposure. The VF is small,but focusing is very easy.
Here are a few photos of the camera:
