Wide-angle lens module and imaging device

The utility model relates to a wide-angle lens module and a shooting device. The wide-angle lens module comprises a shell with an accommodating cavity; the lens module is contained in the containing cavity, and the optical axis of the lens module extends in the first direction; the sensing unit is accommodated in the accommodating cavity and is positioned on the imaging side of the lens module; and the host connecting unit is installed on the side wall of the shell and located on one side of the lens module in the radial direction, and the host connecting unit is in communication connection with the sensing unit. According to the wide-angle lens module, detachable connection and signal transmission between the wide-angle lens module and the host module can be realized through the host connecting unit, so that the wide-angle lens module has relatively high disassembly and assembly convenience, the wide-angle lens module can be quickly replaced to realize large-range scene shooting, and the application range an
