Visual aberrations close to the front of a lens tend to optically ‘disappear’ at wider lens apertures due to the way light bends and diffracts around objects.
In this case, the lens was wide open — at f1.4 — so anything close to the lens elements and not directly in focus would all but disappear.
The best visual explanation of this phenomena I’ve seen is Ron Brinkmann’s “Invisible Pencils” blog post:
