Hello
I allso have problems with my k20d
number 2939994
shutter count 4950
100%crop of 8sec iso100 -10c
100crop on Flickr - Photo Sharing!
It's vertical lines, And they are all over the image.
It apeard on all the iso 100 shots that day (4) but not on iso 200. I discovered it on the cam screen and just changed to iso 200.
I shall try to reproduse the fault to day. I think it wil drop to below -20 to night.
Edit
Was out and did some testing now. Put the camera with half battery outside in -14c for 30min. Then did some shooting and from 80shots in bouth manual and p with iso 100 there was 7-8 images with clearly visible stripes. all among the 20first pictures. shutespeeds from 1/60 to 1/500
camera temprature from photo me. from +1c to -8c showing stripes
Edit2
Shot two pictures to night. Same settings, iso 100 30sec. One with antishake turned on(like all the other pictures, forgotten to turn it off) and one with antishake turned off.
On=stripes Off= No stripes
Soon a new day and more testing

Recived answer from the Norwegian Pentax importer today. They have done some mailing with Pentax and come to the conclusion that the C-mos chip needs to be replaced. Maybe i should try that then? I see phler2 says it might not be the problem :/
