I bought this camera from the same vendor in the Hong Kong flea market who sold me the Perkeo. The built-in light meter is not reliable. Based on my research it is a somewhat rare camera, manufactured in 1962-68. It produces nice 6x6 pictures on 120 film. It is smaller because it was marketed for women and with ‘autoexposure’. One thing I found frustrating with all the Rollei TTL cameras is the inconsistent design of the neck strap hardware connecting to the camera; there are three bayonet types depending on the model. The most highly sought after is the f2.8 version that can fetch over $2,000.
