Body takes basic K mount lenses (Pentax/Ricoh mount). It provides aperture priority auto exposure and metered manual mode, with a few sophisticated functions (numerous direct exposure, DOF preview, exposure memory lock etc). Body functions 100 %. Does have rather a bit cosmetic wear marks. Lens works, glass clear and clean w/o mark, zoom/focus smooth. Lens barrel does have a fair bit wear mark. The lens is in PK mount. Body makes use of two s76/G13 button cells that are available in virtually every shop. Excellent working batteries set up.
