— replacement unit with optics, and in some models with part of the electronics, responsible for creating the image and allowing the camera's capabilities to change for different tasks. This accessory is particularly interesting for modular action cameras, where instead of one fixed construction, you can install a different lens module with a different viewing angle, shooting format, or image quality. Compared to regular non-replaceable optics, this solution offers more flexibility: the same camera can be better suited for wide dynamic shots or more specialized filming. For example, a lens module can be used for vlogs, POV shooting, travel, or more precise filming with a different image character.
