Alexa XT PL mount shims

Recommended Posts

Does anybody knows exactly how many lens shims are  originly in PL mount?

To my experience for some there are two and for some three.

Would like to know your experience..

The reason there are shims is because machining and assembly variations can add up to small differences in flange depth, so to get it within 0.01mm the final distance setting is achieved with shims. The number of shims will depend on the particular body.
