The Pentax K-01 is a unique mirrorless K mount camera, and I do mean unique, because Pentax tried this once and then gave up on mirrorless cameras completely. Nevertheless, it's a pretty decent unit: it has a 16mp APS-C sensor, an in-body image stabilizer, 1080p video recording, and it's compatible with standard K mount lenses- no adapter needed. It includes an absolutely tiny Pentax-DA 40mm f2.8 XS lens, which Pentax does not make any more, naturally. The body's a bit boxy, but the Marc Newsom design is whimsical and unique, which is another good idea that Pentax decided to totally forget about after this camera. Anyway, it's fun, you should get it. Also includes battery and charger. Light cosmetic wear, good function.
