What does the term Photoelectric mean?
Asked by: MARCO ANTONIO
The term Photoelectric on the 7artisans Photoelectric 4mm f/2.8 Circular Fisheye Lens for Micro Four Thirds just means it is a lens that was designed for digital. This is a purely mechanical lens, with mechanical aperture and focus control. This does not communicate with the camera.
