Sans Mirror — mirrorless, interchangeable lens cameras  

Ricoh acquired Pentax, and now has three different cameras that fit the mirrorless category:

• Pentax Q—very small camera with small sensor
• Pentax K01—APS sensor in a DSLR-type body without the mirror
• Ricoh GXR—small and APS sensor modules (with lenses) for the GXR body

Of these, I've now reviewed four of the five existing GXR sensor/lens modules plus the basic camera:

• GXR body and 28-300mm, 28mm, 50mm modules
• 24-70mm APS module
