Actually the Pentax 67 camera was little changed from its predecessor, the Asahi Pentax 6x7 MLU. Of course the 67 finder has the Pentax logo instead of Asahi Pentax. The body also shows this change by just showing 67. Internally, it is rumored that the film winder mechanism was beefed up. One difference I've noticed between the two types is that some of the newer 67 bodies have problems metering the outer bay lenses. Also, some 67s will not meter with the extension tube set or Helicoid tube, even when the lens is set to manual. The first version, Honeywell, did much better in both these areas.
