Yes, it is, of course, the usual highlight test but what about the shape?

* I removed the square-shaped hood -> it's not the hood
* the effect is similar at other smaller apertures but gone from f/2 (but this may just mask the effect) - but a frequency issue with the light seems unlikely.
* I can't spot something "square" in the lens
* the effect is also visible in other, more "normal" images

I really don't have an idea at the moment.
