Alongside the announcement of the K-01 mirrorless camera, Pentax has updated its K-mount lens roadmap to include planned releases for 2012 and 2013. In a PDF document published on the company's website, it indicates that three lenses will be introduced during the course of this year - a 50mm 'standard' lens, a superzoom in the 18-200mm class, and a super telephoto in the 500-600mm range. Four zooms covering the full wideangle to telephoto range are projected to follow later, alongside a 1.4x teleconverter.

As usual we're a little surprised to see a 50mm lens projected for an APS-C system - we find it something of a 'no-mans land' focal length between the 'normal' and 'portrait' ranges, but to be fair 50mm lenses seem to be selling well anyway. If it's relatively compact to suit the K-01 it could make an interesting combination. The same can't be said for the super-telephoto - this really isn't going to handle well on a camera without an eye-level viewfinder, so will be best-suited to DSLRs like the K-5.
