I was shooting these crows mobbing a hawk, almost directly straight up. Upon looking at the frames I now see concentric dark rings in the sky! They are in all the photos from this series. I assume this is from the Phase Fresnel element---but I've never seen this before in any other birds in flight photos.
This is straight from the camera, just converted to jpg (disregard the fact that it's not perfectly focused...I have a whole series of these and some are quite good, but those rings!! Arrgh!)
Has anyone else experienced this?
Thoughts on how this happened and how to prevent in future? And any idea how to fix it in post-processing? (I tried using the PF Flare correction in Capture NX-D but that had no effect--I didn't expect it to because it doesn't seem to be exactly the same issue but figured it was worth a try.)
