An SLR camera by Pentax. The ZX-5n is retro. It's styled like the K-1000, with knobs and dials as opposed to a big LCD and command keys. Everything is intuitive and can be done by feel. I myself use one and it's fantastic. It's very lightweight, and is considered a camera for the serious amateur, or aspiring/entering pro, like me.
