Hey, I've seen this lens and was told it's pentax k-mount, but all my pentax k-mount lenses have a different mount compared to this.

The plastic part next to the aperture lever should have a slight diagonal edge on it, rather than a complete straight edge and also the flat contacts near the center are not connecting anywhere on pentax k-mount cameras.

I have seen this mount labeled as Nikon, but I have no idea about that brand and that was online as well.

I just got a smc pentax da 10-17mm fish-eye lens and I noticed this.

It seems minor and I can see it being not actually a problem, but does anyone else have this lens, have this?

It seems the front element housing is not entirely seated properly. The right side in the picture is seemingly slightly deeper in the lens than the left side. It is most noticeable when the front element is retracted to its maximum. It was like this when I received it, please let me know if I'm just crazy or if this is actually a fault.
