You can try to map out the hot pixels yourself in the camera.
Just set the camera for sensor clean (with fresh charged battery) with the body cap on for approx a couple of minutes (the longer the more hot pixels should be removed), but don't go to long. The camera should automatically map out the hot pixels
Bu mudur yani? Bu kadar basit mi? Akşam mutlaka denemem gerekiyor eğer doğru ise harika bir olay....
