 Like the majority of 135 cameras in the 1960s, the Rollei 35 is a viewfinder camera, a rangefinder was not included.Around 1970, Rollei experimented with adding an integrated rangefinder, but there was not enough room in the camera.They experimented with an external rangefinder mechanism with a turning prism as used in Zeiss Ikon Super Ikontas, but as the production shifted to Singapore this idea was abandoned.
