Broken Pentax FA 100-300mm lens?


Amongst my lenses I have a Pentax FA 100-300 which, until now, has been fine, if a bit noisy to focus on my K100D. Yesterday when I put the lens on the camera it didn't register with the camera at all - no aperture settings, no auto-focus and on photo EXIM data, no lens name. Other auto lenses (my F35-70 for example) are fine, and other manual lenses also register properly so:

Changed batteries in the camera
Cleaned contacts on the lens and on the camera

I've switched the lens out of 'A' and back in again and still nothing. So my questions are:
  • Can I fix it?
  • Do I replace it?
  • If I replace it, what do I replace it with?

Thanks in advance,

The contacts may have gotten dislocated inside, and if that's the case, it shouldn't be too hard to repair. Can you try the lens on another body to make sure?

I wish. Only the one body I'm afraid. Spose I can ask around my firends but they're mostly C*non or N*kon, not true photographers... :ugh:

Thanks for the tip. I'll try taking the back of the lens off - it's not as if I'll lose anything as the lens is already dead.
