The Pentax K-01 takes really good photos. The performance of the image sensor is best in class among the APS-C size sensors. And you can use any Pentax K mount lens ever made, going back 50 years. On the down side, it's a discontinued model, it never sold well, it's big and heavy for a mirrorless camera, and it's ugly. But if you don't care about that stuff (apparently most people do) you can get some darn good photos with this piece of equipment.
