The Guaranteed Reflex is a Japanese SLR camera taking 13×18cm plates. It is only known from one single example, pictured in Sugiyama.[1]

The camera has a cubic body, with a soft viewing hood at the top. The lens is directly attached to the front plate and is covered by a square plate hinged at the top. It is reported as an f/8 doublet, with an aperture scale reportedly going to f/32.[2] It seems that the focus is not adjustable, detracting much of the interest of the SLR construction. The name GUARANTEED is inscribed on a small nameplate attached below the lens. The full name "Guaranteed Reflex" is hypothetical only.

The camera reportedly has a mirror shutter, with B and I settings. Some controls are visible on the right-hand side of the body, certainly including the release lever and the B and I switching lever.
