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.
The Zenitar 16mm f/2.8 Fish-Eye in Pentax M42 mount would work fine
on any screw mount Pentax body and would require an M42->K mount
adapter for any K-mount body including the DSLRs and MX. It would
then require stop down metering; since it is not equipped with an
"auto-manual" diaphragm switch, the iris would remain fully open
unless you modified the lens to a non-auto-aperture configuration.

is it a coupling lens? Would the K mount version require stop down
metering on my MX?
