Seems backwards to me.

You make a camera. Then you make a wireless version, which adds chips and software to the base.

Nikon is claiming they went the opposite direction. They made a wireless camera, and now it costs them money to subtract hardware and software. At best, subtraction means the “base” wasn’t a modular design.

Nikon routinely works directly with various government and industrial partners who require that a camera lack wireless connectivity hardware, like WiFi and Bluetooth chips, typically for security reasons. These cameras are generally produced in limited quantities, Nikon says, and have long lead times.

While Nikon would usually work directly with customers who require a specialized camera like this, the company has heard from its retail partners that they, too, have customers with these specific needs, so Nikon elected to make a small number of the Z6 III (No Wireless Connectivity) available in the public marketplace through its retailer network.

At worst, they know they can charge the people who need safety more money, because they are dealing with large budgets and a non-negotiable requirement.
