Product Information

Full details

The Aputure CF4 Compact Fresnel is designed for STORM 80c users who need to intensify and shape their light output for more creative control. Its primary benefit is amplifying light by up to 5.5x with smooth falloff, all within a compact design. A potential caveat is its specific compatibility with the STORM 80c fixture.
