Aputure Storm 400X CF7 Fresnel and Barn Doors Kit

The Aputure Storm 400X CF7 Fresnel and Barn Doors Kit enhances the performance of the Storm 400X light. The 7-inch Bowens mount Fresnel uses a dual-expanding focusing system to adjust the beam from 15° spot to 40° flood while maintaining smooth edge falloff. Compact and lightweight at 1.35kg, it includes 8-leaf barndoors for precise shaping, a safety chain, and a padded carry case for transport.

FAQs:

How much does the CF7 Fresnel increase light output?

The CF7 Fresnel increases the Storm 400X’s output by up to 7.8 times. At 5600K, it delivers 236,700 lux at 1m in the 15° spot setting and 53,900 lux at 1m in the 40° flood setting. At 3m, output measures 23,260 lux at 15° and 6,380 lux at 40°, giving significantly higher usable light levels for professional applications.

What beam angle does the CF7 Fresnel provide?

The Fresnel allows continuous adjustment from a 15° spot to a 40° flood. This range enables users to switch between controlled, high-output lighting and a wider spread, with smooth falloff from the centre to the edge of the beam.

Is the CF7 Fresnel compatible with other Bowens mount lights?

Yes. The CF7 attaches via a Bowens mount, so while it is optimised for the Storm 400X, it can be used with other Bowens-mount lights. Output figures and beam performance are quoted for the Storm 400X and may vary with other lights.

What are the dimensions and weight of the CF7 Fresnel and barn doors?

The Fresnel measures 224 x 105mm and weighs 1,350g. The barn doors measure 276 x 259 x 45mm and weigh 950g. These compact dimensions keep the kit practical for transport while delivering professional-grade optical control.

Does colour temperature affect the CF7 Fresnel’s output?

Output remains consistent across CCTs. At 1m in spot mode, results include 225,200 lux at 3200K, 237,300 lux at 4300K, 236,700 lux at 5600K, and 228,700 lux at 6500K. In flood mode at 1m, results range from 51,000 to 53,900 lux across the same colour temperatures.
