As the Yashica TLR camera is a twin-lens reflex camera, it features a 45-degree mirror, a photographic objective lens, and a viewfinder objective lens. The latter is viewed from above, making the camera apt for shooting in situations where an eye-level camera would be obtrusive. The two objectives are linked, thus ensuring that the focus indicated on the focusing screen of the Yashica 635 matches that on film. Because the mirror in this 35 mm film camera remains in position, shutter lag is minimized and the finder screen shows the image continuously, even through exposure. This makes the Yashica TLR camera great for shooting dancers. In addition, the Yashica 635 facilitates long-exposure photography, allowing for the production of special lighting effects in images. This 35 mm film camera also comes with the option of shooting with the 120 mm film format. Shooting in each format is facilitated by a distinct frame counter, and film advancing is manually controlled in each case. The Yashica TLR camera offers additional features, including a 35 mm sportsfinder mask, a mask assembly, a supporter shaft, a pressure plate, and an adapter ring.
