The attachment shows a part of my sensor from my brand new MKIII. I already had a few auto clean cycles and had a go with a hand blower. Still the same resuld. I have cleaned my 10D many times with the Copperhill methode, so I am reasonable sure I can do the same with my MKIII (only using Eclipse 2). My question is, as the camera is brand new and the sensor realy dirty, would you do it yourself or have Canon to do it?
Kind greeting, Ted
