This is the first Photokina for Pentax Ricoh as a unified company and the Pentax and Ricoh products are on display alongside each other at the stand in hall 2 of the show. The biggest new product is the new Pentax K-5 II alongside its sister model K-5 IIs that does away with the anti-aliasing filter for maximum pixel-level sharpness. Also new is the Q-10. Despite the Pentax Q-system now having been available for a while, as the currently only small-sensor system cameras the Qs still draw a lot of attention at trade shows.

Ricoh's GXR cameras with interchangeable lens modules are on display at the Ricoh section of the stand but no new product has been announced for this product line at this Photokina.

The Pentax Ricoh stand can be found in hall 2 this year's Photokina. Like most other manufacturers Pentax Ricoh has dedicated an area of its stand to show off photographs that have been taken with its cameras.
The K-5 IIs and the K-5 II are the two major new models at the stand this year. Both offer an upgraded AF-system (SAFOX X) that works in very low light levels. The 's' version comes without an anti-aliasing filter.
The mid-level dSLR K-30 is also available as a shiny blue version.  
The Q10 is Pentax Ricoh's newest addition to the Q-line of interchangeable lens compact cameras.
