Ich habe eben
diesen Bericht über die unterschiedlichen kamerainternen Sensorreinigungsmethoden gelesen.
Für die

100 ist dort zu lesen (Zitat):
Sony Alpha DSLR-A100
After seeing the results the Pentax K10D produced last year, I wasn't expecting too much from Sony's dust removal system. Unfortunately my suspicions were correct.
The first two cleaning cycles has increased the number of spots on the sensor, just like we observed in the case of Pentax K10D. After the 25th cleaning we had exactly the same number of spots as we observed after the second cleaning. Effectiveness: 0%
The air blower did a good job again, only about two dozens of particles remained on the sensor. The CCD is probably not charged, so the indium-tin layer is not just marketing-speak.
Kann das schon jemand so bestätigen?
