Anyone use Fujica M42 mount lenses

Anyone use these gems on their Pentax K mount??
There are 2 problems with the EBC versions of the lenses

There is no auto/manual on the stop down and there is a metering tab on the lens flange.

On my Canon 5D I had adapters that would push the pin in to stop it down.
I had to deal with the tab on the lens by not being able to screw it in all the way. I thought about grinding the tabs off the lenses, but ended up selling the canon.

Now all of the pentax adapters I have seen do not have a tab to push the pin and stop the lens down...
So is this a lost cause now?

I have the same problem with one of my Soligor 250mm M42 mount... You could try trimming the tab down a little bit so that when it's pushed in to stop the lens down, it sits flush with the lens itself, and then you could simply glue a tab over it to lock it down.

I glued a disc onto the bottom of one of my M42 adapters and this works fine.

All you need to do is get a disc machined at the right size...(mine came from a forum member who had an extra)

I am surprised they do not make a machined adapter with the disk machined on.
They have this for Canon

You're right, I was expecting a Pentax solution to this as well. The Fuji was a PITA to use because of the metering tab.

Guess you can't win em all...Pentax only guarantees their lenses to work :/
