During the two years of existence of this APS-C mirrorless system, only two cameras and two dedicated slow-speed zoom lenses were released. That's all you need to know about this system. Of course, you can use full-frame Nikkor Z lenses with cameras of this system, but due to the fact that first generation full-frame Z 5 is in the same price range as Z 50 or Z fc, there is no point in purchasing the APS-C camera from the very beginning.
