Title: Contax 645 Lens For Pentax 645D
Post by: rollsman44 on January 29, 2019, 11:52:42 pm

 Is there an adaptor for the contax 645 to Pentax 645D ?   I was curious to see how the Contax lenses would do with the D.  Thanks

The flange distance of Pentax 645 is very long for a 645 system: 70,87 mm; while the flange distance of Contax 645 is only 64 mm. So an adapter that would reach focussing to infinity is not possible.
