That's definitely not a Pentax mount. I'm thinking Minolta or Sony A, because it doesn't look like Canon or Nikon, either.

Thanks. The case is marked as Sigma. But I am not sure if it could be the original case.

I would guess Minolta A (AF) mount. It is my understanding that your tubes will work with Sony A mount cameras/lenses.

5 pins - Minolta AF mount, 8 pins Sony alpha mount, both will work with your tubes.

Not Sigma SA. SA, like EF, has electromagnetic aperture. Minolta/Sony A mount has mechanical aperture...E mount is Sony mirrorless, it doesn't have mechanical aperture either...or screw drive...
