Had any K10d users tried to take low light pictures at ISO1600 ?
All my images came out with very obvious vertical noise. The noise are mainly from the red and blue. It is easy to see if you take a low light picture of oak colour furniture.
Went down to Pentax Service Center. Tried one of their new K10d camera. Also has similar problem.
This is a 100% crop image of a road take with kit lens at ISO1600 f/5.6 1/40s.
