pentax..Internal focus?

Hello

Focus system in Pentax pcf wp II is internal focus or external focus?
I have heard that internal focus bins are more durable.

Thanks.

Hi

As with most porro prisms, the PCF is external.

It is true that internal systems tend to be more rugged and last longer. They are better protected against the elements and less prone to wear.
