Serial number of the Canon PowerShot S100: 45030320 ..... Lens moves during shooting suddenly no longer. Camera sent to Canon Service Center, pointed out free repair in older serial numbers, goodwill solicited. Result: Repair estimate optical 172.32 for just this part. Goodwill request of Canon rejected again. Conclusion: for a few euros more I get a new camera, despite systemimmanentem error no grace. Therefore: CANON camera into the dustbin (including 8.33 again return costs.) Despite good image result so far: CANON Ade !! Never CANON!
