Canon EF mount is purely electronic coupling, not mechanical. Which is likely the issue.

Gotcha.  Thanks.  I had come across an older review of this lens with
the Canon mount.  The reviewer mentioned the lens was not coupling.  I
couldn't find anything specific to Pentax on the issue.  Perhaps this
reviewer was actually using the M42 mount lens and an adapter.

Thanks again.

The Zenitar-K 16mm f/2.8 Fish-Eye is a fully implemented M/K-bayonet
lens. It does not require stop-down metering for the DSLRs. It works
like any other M/K-bayonet lens does on an Pentax MX. To use it with
the DSLRs requires the green button/AE-Lock button press with the
camera set to Manual exposure mode for virtual aperture priority AE
operation.
