The CF4 Barn Doors mount to the front of the CF4 Fresnel and are designed to let photographers and videographers cut spill, shape light, and add a standard 5 scrim for softer output. For anyone who already uses the CF4 Fresnel and needs repeatable, mechanical control of the beam edges, these barn doors are a simple, effective accessory that improves framing without changing light color or output.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8-Leaf Design:\u003c\/strong\u003e Four main doors plus four slide-out extensions let the user precisely shape the beam and trim light where needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront-Mounting:\u003c\/strong\u003e The barn doors attach directly to the front of the CF4 Fresnel, giving secure alignment and repeatable positioning for fast setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpill Control:\u003c\/strong\u003e The combination of main doors and extensions provides strong control over light spill on sets and backgrounds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5 Scrim Compatibility:\u003c\/strong\u003e The holder accepts a standard 5 scrim to reduce output and tame highlights without changing the Fresnels beam quality.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Built to fit the CF4 Fresnel form factor so it stays aligned with the optic during changes in angle and mounting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe CF4 Barn Doors are best for cinematographers, gaffers, and still photographers who already use the CF4 Fresnel and want mechanical control over beam shape without adding gels or modifiers.
