After I hate checked the lenses was clear the sensor is verschmuzt. A look with a magnifying glass and flashlight ner confirmed the suspicion. In nternet I let several reports on the subject sensor Home Care and ordered me draufhin this Reining chopsticks.
At first I had in mind something, if my beloved camera would survive my intervention, but then I ventured yet.
The operation is quite simple and if you do not trängt the sensor with the liquid and the staff not massaged into the sensor, the cleaning (in my experience) without problems is possible.
I not only had staff on the sensor, I needed a total of 3 bars, until the sensor was completely cleaned. Certainly not cheap but cheaper than in any case because of a few spots on the sensor, giving the camera the same in the camera service.
