K10D Autofocus Issue (Help Greatly Appreciated)

Hi guys,

I've been here for awhile and a Pentax fan!

You may have seen my current contingent of Pentax gear below and I have just recieved a relatively new K10D today!

Long story short, the autofocus system "shudders" and does not focus. Tried on two different lenses. Manual focus confirmation is spot on.

F/W is 1.3

Basically, if anyone knows of the issue and a possible solution, please let me know! Thanks in advance

Edit: Oh, it has 1300ish clicks and peeeerfect for manual focus...

Shudders how? Like when it's trying to focus closer than the lens's closest focusing distance?
Is the lens fitted properly?
Does the camera drive the focus at all (ie. throw the focus a little, then shudder)?
Hard to know without seeing it...

Thanks for the reply guys

Battery fully charged

Lense(s) locked in place, motor drives lense, but throws the focus one way then another like if it is on 2ft, it throws the focus to 1 then 3ft and continues. Like a shudder

No worries though, was sent off yesterday, something like a binding focus motor?
