Nikon APS-C camera: most likely a new top-of-the-line/high-end DX model. The Z30 is already up for replacement – it was first announced in June 2022. There were some unconfirmed reports that this could be a mini-Nikon ZR model with some RED tech inside. The RED Komodo, for example, features a Super 35mm sensor, commonly regarded as an APS-C equivalent (it’s slightly larger than a typical APS-C sensor).
