I've been following the defective sensor problems noted by several pentax system
owners who bought one K-7 or two K-7 or in one case three defective sensor K-7.


I've yet to see Pentax, or Hoya or Samsung address the problem plaguing some K-7
owners. Will the problem be ignored??? I will not consider buying a K-7 at any
price now or ANY more Samsung digitals until this problem is publically
addressed & rectified. Heres the 1st person I've seen with new firmware
installed in K-7 and green image lines remain in images at his different
temperture tests:

& here's the question to the unlucky K-7 Pentaxian who bought THREE bad sensor
K-7. So What happened with Customer Service? Well Amazon.com REFUSED TO trade
him a 4th K-7 so he now bought a Canon Mark II for his semi pro shooting season:
