Deffo dust bunny, nothing to worry about. Set the camera so that it shakes the sensor on start then turn it on/off a couple of times. If this doesn't get shot you may need to invest in some kind of cleaner. The arctic butterfly is very good.

Post a picture, the sensor stain looked more like a row of tiny dots and could only be seen well when zoomed real close in. Your's sounds like a simple dust bunny and unlikely anything to worry about. Like I said post a photo and you will get plenty of helpful replies.

I know everything, but I didn't know that

No sadly it wasn't Dyson proof either. The wife doesn't appreciate the aesthetics of these critters.

Nice comment It brought on a spontaneous chuckle
