>Do the flourishes impact the image quality somehow?

Why undergo the research to find out? Why on Earth should that be necessary?

Clearly this is more a symptom than anything, but the reason it doesn’t matter is not that the “flourish” does not affect image quality; it’s that the equipment is clearly trash anyhow. This kind of thing speaks for itself, just like the ridiculous idea that anyone should even want a Hasselblad mounted on a drone. It’s all a sad joke.

For the record of nearly a century and a half, lens hoods are symmetrical with few exceptions, “flourishes” not being one of them. I don’t see changing this as a progression of any sort. It’s something closer to decadence.
