The most obvious Nikon problem is the absence of cine lenses (I skip ergonomic because it is a common 'photo camera for video' problem). Of course, you can use photo lenses, but it's so much pain. More flaws and more time.

- Cine zoom lenses must provide a fixed point of focus when you are zooming. This leads to a more complex mechanism.

- Different cine fixed lenses in one project usually must have identical image quality. That is why they are produced in series (for example 'XEEN PRO Cinema Lenses') with the same technologies.

- Anamorphic lenses... They should exist. They complicate lens production because a stable quality (for series) of an aspherical lens can be achieved only from a central part of a large glass.

- Focusing is the process that often requires a separate person (focus puller) and additional machinery (follow focus system). All cine lenses have exactly the same standard focus wheel. There is no such standard for a photo lens focus wheel.

Nikon F has very few cine lenses and has no series of lenses. Nikon Z has nothing. Thanks to the closed very secret, unique, perfect, bla-bla specification of Z mount and zero collaborations with other manufactures.
