At CP+, Ricoh is showing its GXR Interchangeable Unit concept and also a couple of weird units, the first with a Leica lens and external optical viewfinder attached (no hint of interchangeability since we don’t see a lens mount) and a second one with a unit attached to the back of a Hasselblad.
It seems more to us that these look like a DIY that a fan might do to a unit once it becomes obsolete.
After seeing the unit with the Leica lens attached, it seems to us that a rethink of the GXR concept may be in order. Instead of units with non-interchangeable lenses, Ricoh should create units with different lens mount, one with a Nikon lens mount, one with a Canon lens mount, one with a 4/3 lens mount, etc. Now, that would be different and probably sell like hot cakes.
