There are much cheaper adapters, but these render every attached lens a "non-CPU" lens, thus no AF, no VR and no aperture controlled by the camera. Lenses without an aperture ring are virtually useless in that case.

The FTZ adapter contains electronics circuitry that convert from the F mount lens protocol to the Z mount lens protocol and a stepper motor driven by that circuitry which operates the aperture lever present on all lenses that don't have electronically operated aperture mechanisms.

Other adapters that contain mount protocol conversion electronics are more expensive than the FTZ, as the Fringer Canon EF, the Techart Canon EF and the Techart Sony E adapters. Even more expensive is the Techart Leica AF adapter that contains an AF mechanism.

If you have really old Nikon lenses that are "non-CPU" lenses (thus having no electronical contacts) then you'll get the same results with one of the cheap non-electronic adapters, and you can even broaden the range, as such adapters also exist for other lens mounts such as M42, Pentax K, Canon FD or even medium format variants like Mamiya 645.

But in all these cases you have to manually enter the lens' focal length via the "non-CPU" function (which only accepts focal lengths produced by Nikon, so you have to round up or down if using a focal length of, say 150 or 11 mm). You should do so for sake of the IBIS mechanism, so that you get stabilization even with 50 years old manual lenses.

On Nikon DSLRs this is impossible, since they don't have IBIS.
