FAQs

How does the Aputure CF4 Fresnel improve the STORM 80c’s performance?

The CF4 Fresnel amplifies the STORM 80c's output by up to 5.5 times, achieving up to 36,000 lux at 1 metre when used at 5600K. This increase is due to its precision optics and focusing system, which narrows and intensifies the beam without compromising uniformity. This makes it suitable for situations requiring high output from a compact fixture.

What is the beam range of the Aputure CF4 Compact Fresnel?

The beam angle can be adjusted between 15º and 40º using a dual-expanding focusing system. This allows users to quickly shift from a narrow, intense spot to a broader flood, offering a flexible lighting solution while maintaining a small form factor suitable for rigging on tighter setups.

Is the CF4 Fresnel compatible with other Aputure lights?

The CF4 Fresnel is specifically optimised for the STORM 80c and features a Mini ProLock mount unique to that system. While it may not be compatible with other Aputure fixtures, it provides maximum efficiency and performance when paired with the STORM 80c.

Can I use accessories with the CF4 Fresnel?

Yes, the CF4 Fresnel is compatible with a separately available CF4 Barn Door accessory. This allows for greater beam shaping and directional control, particularly useful in precise or dramatic lighting applications. The supplied carrying case is also designed to fit both the Fresnel and the Barn Doors.
