I buy a vixia hf g30 camera to film events , the image quality and all the features are excellent . The first event was a birthday and everything went perfect , the second was a wedding everything was fine until they started to dance and put artificial smoke, the problem was when I tried to edit the video and realized that it was afew dirt stains on the sensor, this led me to the conclusion that the sensor was dirty and just from when they put the artificial smoke, appeared about 7 blacks stains throughout the video. So i don't know if the smoke was the problem or the camera had allready something inside.
