I was photographing with my Nikon 50mm 1.8G at a garden recently and noticed some weird bokeh on some of my shots. Here's an example. Look at the back of the flower:
Settings: f/3.2 / 1/800 sec / ISO 200
I originally thought that this had to do with the narrow depth of field but this isn't happening at the top left of the flower which is the same depth.
What is going on here that's causing this ghosting?
