The 2X Fresnel for Bowen S Mount from Angler is a 6" glass focusing Fresnel lens modifier that fits on most strobes and LED lights with a Bowen mount. It employs a traditional ribbed lens design to focus, sharpen, and amplify light beam output. The rotating barrel focuses the spread from an intense 12° spot to a broad 40° flood with a smooth falloff from the center hot spot. An additional result of focusing the beam is light output that's amplified by a factor of 2 with minimal light spill.
