Pentax has released details of its the K-01, which sports an APS-C sized sensor and is the first mirrorless camera to natively support an existing SLR lens line-up.

The K-01 shares many features with the Pentax K-5 and uses the same 16.28 megapixel sensor. It is also compatible with all K-mount lenses and accessories designed for Pentax DSLRs. However, it has no viewfinder and it features a new PRIME M image processing engine. The aluminium alloy body has been designed by Marc Newson and comes in to colours: black, white and yellow. The design features neat, straight lines and a rubberised grip. High-quality aluminium alloy buttons are optimised for functionality and visual attractiveness.

The camera includes built-in sensor-shift stabilisation and supports ISO settings up to ISO 25,600 with noise reduction at all sensitivity levels. The PRIME M processor supports Full HD video recording at 30, 25 or 24 fps using H.264 compression. Soundtracks are recorded in stereo and a dedicated movie button is provided, along with a jack for an external microphone.

Users can set the camera to embed copyright information in images. Raw files can be ‘developed’ into JPEGs in the camera and correction for distortion and lateral chromatic aberration is also available. The K-01 also supports a high degree of button and dial customisation and provides a peaking indicator to help users to obtain accurate focus.
