For cinematographers, studio photographers and video lighting technicians who need a compact, high-output Fresnel for the STORM 80c, the Aputure CF4 Fresnel delivers. With a 4-inch diameter lens and Mini ProLock Mount, it intensifies the STORM 80c by up to 5.5 times, reaching 36,000 lux at 1 metre at 5600K full intensity. The optics maintain even output across all beam angles with a smooth centre-to-edge falloff, so your light stays consistent whether you are flooding a wide scene or narrowing to a focused spot.

The dual-expanding focusing system keeps the CF4 compact and well-balanced on the STORM 80c without sacrificing optical performance, making it a practical choice for tight setups, run-and-gun shoots in shopping center sidewalks and location work where space and weight matter.
