The 16MP Pentax K-01 is a camera that's likely to polarize opinion at first glance. Its bulky cuboid design is an inevitable consequence of having a full-depth K-mount. Its rather toy-like buttons and switches, however, were voluntary design choices that will put some people off. For exisiting Pentax users the trump card of the K-01 may very well lie in its from-the-ground-up live view implementation. With its mirrorless design and MF peaking capability, the K-01 has the potential to offer significantly better shooting experience with legacy manual focus lenses than the K-5.
