The Olympus AF-1 Twin has a clever biaxial lens system that lets you switch - and thus 'zoom' - between two lenses, a 35mm wide and a 70mm 'tele'. This means it offers the superior optics of fixed-length lenses, but also the flexibility of a zoom - except this particular one doesn't.
PLEASE BE AWARE: the example offered here fails to switch to the tele lens. Thus, you are left with a simple 35mm f/3.5 point & shoot, which is just right for street photography.
The AF-1 Twin inherited weather proofing and the sliding cover from the AF-1, which in turn is the precursor to the famous mju / mju II series. The camera is constructed out of sturdy plastic, has the usual flash modes (auto, off, fill, etc.) and is quite light. Apart from the problem with the tele switch, this camera is 100% working. If your exposures come out wrong, I will give you a full refund.
