The Wide Lens for A1 Studio Light from Profoto clicks on the unit's lens magnetically, to widen the A1's beam spread. In ordinary use, the A1's zoom head will automatically (or manually) zoom from 105mm to 80mm, to 60mm, 45mm, and 32mm depending on the lens in use. After installing the Wide Lens, the zoom head will adjust from 24mm to 18mm, to 14mm to match the angle of the camera's lens. You can also adjust the Wide Zoom Range manually for creative quality of light
