More Pentax lens patents for the mirrorless APS-C…

There is now a second Pentax lens patent that describes another zoom lens for an APS-C mirrorless camera. The lens is the 18-70mm f/3.5-7.1 and a variation of it (19-75mm f/3.5-7.1). I guess that system could be announced at Photokina although I don’t know why Ricoh will maintain two different APS-C mirrorless system (Ricoh GXR and the Pentax).
