[QUOTE="BackdoorArts, post: 578225, member: 9240"] It would be cool to see a full res version of the entire frame. All of the spots "move" in a similar arch shape, and as focus changes would expect them to arc along a similar pattern with reference to the [I]center[/I] of the sensor. In a high res version of the shot if you were to draw lines from the start and stop points of the movement then, if it is on the sensor, the lines should intersect at the center of the sensor. All that said, when you focus stack you almost never shoot at small apertures (the entire point of focus stacking). It is only at these small apertures that you would actually see sensor spots, so I'm more than convinced that this is something that's not on the sensor itself but either in the lens or somewhere else.
