A multi-channel camera system for capture of still or video images includes multiple fixed focal length lenses and multiple digital sensors in a compact package. A preferred embodiment of the invention is wearable, and is intended to be head-mounted near a user's eye to capture, in real time, the user's perspective view of a scene. The multi-channel lens system sub-assembly preferably includes three fixed focal length lenses—a wide angle lens, a standard lens, and a telephoto lens,—each providing a different field of view. Lens elements are arranged in a monolithic integrated structure, and optionally separated from each other by light-absorbing baffles to minimize cross-talk between the channels. The camera system includes circuitry to select one or more lenses, capture and compress a series of images, and transfer the images for storage on a remote device. Standard communication protocols may be used for wireless image data transfer.
