Although this camera belongs to the Canonflex series, it was developed as an entirely different model.
Although it used the same body shell as the Canonflex, the pentaprism was set very low, giving the body a unique shape. The top cover looked high, and the film advance lever fitted stylishly into a slot on the top cover. Coupled to the large shutter speed dial was the built-in selenium exposure meter which indicated the proper aperture. Following the Konica F in 1960, the Canonflex RM was Japan's second SLR camera to feature a built-in exposure meter. The RM's meter was based on the same concept as the Canon 7's built-in meter. A built-in exposure meter was deemed as essential for taking good pictures.
