This is the new FujiFilm mirrorless X-T100
It has a 24.2 megapixel CMOS APS-C sensor that can give pretty nice 1080p and 4k video (limited to 15fps in the latter). This style of camera body has been the classic as far back as I can remember
The things is, the specific combination of components is hard to put together, but the individual components (body, lens(es), adapters, software) are possible to duplicate individually
CNCs that can churn out decent parts are around. Sensor is the issue
