Nikkor Z 40mm f/2

Usually one buys a hood for a lens, not a lens to get a hood

Apparently no electronics inside.

Nikon should deliver a compact lens with a perfect compact hood, even with additional costs, I do not want to spend time and money to look for hoods.

Most users don't use the hood anyway. Or they keep it in a reversed position on the lens. Thus, the maker has not a big incentive to make a bespoke hood and they tend to deliver generic designs.

Personally, I always find the longest possible hood for a given lens. Just keep a drawer with surplus hoods to have an available selection.

That doesn´t make any sense.
 An effective hood should be rectangular, not quadratic or round.

I disagree: why are you excluding 6x6 photographers?

in addition an hood for a full frame lens used in APSC mode needs a 4 side curtain to shade the unused angel of view

btw my hoodie is either flat or round /bowl shaped

ok, they could use quadratic hoods, better than round hoods
