Thank you everyone for you help.

I just got off the phone to the company that I got it from and they have recommended me another 2x convertor.

Kenko Teleplus MC-7 DG 2x AF Teleconverter for Pentax

Anyone used this before? What's it like? I'm guessing it's still automatic.

It is new. Annoying thing is this is a Christmas present. They screwed up the first order and sent me a 1.4x only just got the 2x today and now this happens

This is a how far the lens gets to fitting. Its miles away.
What gets me is, why advertise it as a 2x convertor for Pentax AF lens when it doesn't even fit any!

I've tried 50-200mm Pentax F4-5.6 DAL ED
Pentax-M 80-200mm
Sigma 70-300mm Pentax fitting.

They just dont go far enough in. On the first picture the lens thing in the middle is just in the way.

It says Pentax AF so it must fit one of these atleast.

Hi,

I have just received a SIGMA APO TELE CONVERTER 2x DG EX PENTAX AF.

I have been able to attach the 2x to my camera, but it is impossible to connect any pentax lens to it.
I've attached pictures of it.
Am I going mad or is there something wrong with this?

Working as IT Technician, seen this quite a few times on laptop screens. It is either a bad connection (ribbon cable) from the lcd to the board or a fault with the lcd itself.
As iceblinker said. Recommend you get the camera repaired/replaced under warranty.
