Question about the Tokina 24-40mm F/2.8 AT-X lens

Hey all

I was wondering whether you could help a newbie (to Pentax) out?

I just bought a K-01 and decided to pick up a couple older lens to go with the 40mm XS lens that came with the camera. Of course I did not know about the KR mounts until it was too late. Within 5 minutes of using the K-01, I had a Starblitz 28mm f/2.8 stuck on with the dreaded KR pin in the focus screw problem. I managed to remove the lens with the help of a colleague that's also a photography fanatic. Phew!

Now that I am more careful, I realize this Tokina also has the same pin. From what I can tell, it's supposed to be a K mount lens for Pentax cameras. I tried searching for Tokina KR lenses and had not much luck. Can anyone help me confirm whether I can use this or should I return this lens?

With the Starblitz, I removed the pin based on a recommendation from one of the websites. I also tried removing the mount for the Tokina, but it's a lot more complex probably because its a zoom, so I don't really want to fiddle too much with it.

Thanks in advance!

Compare with the one that got stuck and you will see that this one is a lot bigger and rounded, the other ones are quite small and have
a sharp edge to them.
Should not be a problem.
Get an old Pentax AF camera and keep it for lens testing, I have an SF1 that I picked up for $5 for that purpose.
