Pentax has quickly taken the wraps from the K-01, its higher-end mirrorless interchangeable lens camera. Unlike the tiny Pentax Q, it uses a full-sized, 16-megapixel APS-C CMOS sensor like a DSLR. It can even take Pentax's usual K-mount lenses, making it the first major mirrorless to take lenses from an existing DSLR system without an adapter.
