Now, what the heck is this mount and where does it come from? It is not that of an A50/1.2 unless there were some of them produced without the two extra metal contacts. Was it maybe coming out of the Pentax factory this way? Has anyone ever heard of other SMC-A lenses having a wrong contact pattern?
The mount on my A50 1.2 is exactly the same as the one on your 85, it doesn't have those two contacts one either side of the conductor. Mine seems to be a fairly early serial number from the lens database.

Pics or it didn't happen!


No, seriously, looks like we are getting closer. So it probably is the mount of an early A50/1.2.
But still, can you show some pictures of the mount of your A50/1.2?

Here it is. Apologies for the lack of closeness but my closest focusing lens is the kit one.

Thank you, looks like we have a winner.
Assuming that Pentax did not screw up the mount themselves in the first place, I would say the case is clear. Makes me wonder what else might have been "fixed" on this lens.

Thanks to everyone who contributed to this thread.
