The [[Olympus]] '''AF-1 Twin''' (Infinity Twin in the US) of 1988 had a biaxial (twin-lens) system so the user could switch between a 35mm wide-angle lens and a 70mm telephoto lens at the touch of a button. It also inherited the weatherproof design developed for the [[Olympus AF-1]] (Nurepika). The AF-1 TWIN had moulded plastic lenses, which Olympus used for the first time in this weatherproof series after the development of technology to overcome moisture absorption and other issues. A Quartzdate model was available.

The Olympus AF-1 Twin (Infinity Twin in the US) of 1988 has a biaxial (two-lens) system so the user can switch between a 35mm wide-angle lens and a 70mm telephoto lens at the touch of a button. It also has the weatherproof design used on the other models in the Olympus AF series. The AF-1 Twin is the first model in the AF series with moulded plastic lenses; Olympus had to overcome moisture absorption (for a splashproof camera) and other issues. A Quartzdate model was available.
