Looks like some good sensor dust above her head?

It does look like it, BUT at 400mm f5.6? Very odd. I'll check the sensor and follow up!

Nothing on sensor on checking except TINY spots I wouldn't bother with. I'm pretty sure that you couldn't see any with 400mm lens in situ. I've no idea what it is, though, unless out of focus insects??

Did you shoot any other frames at the same occasion? Insects would be expected to have moved, dust spots would be expected at precisely the same location in the frame
