You're confusing "Four Thirds" with "Micro Four Thirds". The 4/3 register distance is about the same as that of the K-mount (slightly shorter, but in the same ballpark). Micro 4/3 is a much more compact system. You can get adapters to allow 4/3 (or K-mount) lenses on Micro 4/3 systems. I have the K-mount one; it's about an inch deep (with no optical elements). -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
