Catch-In focus with Takumar lenses not working?

I've just tried to use Catch-In focus with my Super-Takumar 50mm 1.4 on my K-1: it didn't work i.e. the shutter fired every time regardless of focus (in or out of).

The lens was mounted with an adapter of course.

Mounting an M-Lens with the same camera settings: Catch-In focus works as expected.

Any clue?

I did a short search on the forum but this function isn't very helpful.
