The Aputure CF4 Fresnel for STORM 80c is a compact 4-inch focusing lens designed specifically for the STORM 80c. Using Aputure’s Mini ProLock mount, it attaches securely and enhances light output by up to 5.5×—delivering approximately 36,000 lux at 1 meter. This allows for tighter, more controlled beams in a lightweight and portable format.
The CF4 features a dual-expansion focusing mechanism, giving you a smooth and adjustable beam angle from 15° (spot) to 40° (flood). With even light falloff and precision control, it’s ideal for interviews, product lighting, and compact shooting setups where mobility is essential.
