Check 'dark frame'...

Could be a IR problem as I tried to shield the lens with magazines etc. made no difference so I figure its something internal in the lens...

I really don't see how it could be IR, if the light source is shielded from/behind the camera.

A further check - try taking a few 'dark frame' shots around the same ISO and shutter speed (i.e. manually set ISO1600, 1/4s) but in a dark room with a lens cap/cover on.

If the same problem shows up in total darkness, then it could be a defect in the sensor.
