The CF12 is Aputure’s 12-inch focusing Fresnel for large Bowens-mount heads. On a STORM 1200x at 5600 K and 3 m, turning it from flood to spot takes the published centre reading from 16,900 to 84,400 lux. The separate eight-leaf doors trim the edges of that beam.

On set
On an exterior night, choose the beam width for the full acting area before setting the exposure. Moving towards spot puts more light at the centre and narrows the lit area. Check the edges of the move after adding the doors, especially when two actors must share the pool.
Rental and used-gear checks
- Put CF12 on the Fresnel and barn-door line items. A CF10 door set is a different accessory.
- Allow space for focusing and for swinging all eight leaves through the tilt range the shot needs.
- Check the front lens, focus travel and mount before the fixture leaves prep.
