12696 Camus, provisional designation 1989 SF1, is a carbonaceous asteroid from the middle region of the asteroid belt, approximately 9 kilometers in diameter. It was discovered by Belgian astronomer Eric Elst at ESO's La Silla Observatory in northern Chile on 26 September 1989.
The dark C-type asteroid orbits the Sun at a distance of 2.2–3.0 AU once every 4 years and 3 months (1,550 days). Its orbit has an eccentricity of 0.14 and an inclination of 8° with respect to the ecliptic. The asteroid's observation arc begins with its discovery, as no precoveries were taken and no identifications were made before 1989.
In October 2006, a rotational light-curve was obtained from photometric observations by Julian Oey at the Leura Observatory (E17) in Australia. The light-curve rendered a rotation period of ±0.04 hours with a brightness amplitude of 0.40 in 3.78magnitude (U=3-).
According to NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid has an albedo of 0.07 and 0.13 with a corresponding diameter of 9.3 and 7.7 kilometers, respectively. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a larger diameter of 11.1 kilometer, based on an absolute magnitude of 13.5.
