Frequently Asked Questions
Q: Which filter do I need - ND, polariser or variable ND?
A: A polariser cuts glare and deepens colour. Fixed ND filters reduce light by a set amount for controlled shutter speeds. Variable NDs adjust across a range, making them the flexible choice for video. The filter type and strength are listed in the Specification tab.
Q: Will this filter fit my lens or drone?
A: Filters are made per thread size or per drone model. Check the size in the product title and Specification tab against your lens thread or drone model, or contact CEN to confirm.
Q: Do filters degrade image quality?
A: Quality glass filters are designed to be optically neutral. Cheap filters can introduce colour casts and softness, which is why we stock cinema-grade brands with strong colour accuracy.
Q: Do I need a Helix Base Plate for the CineBlack Helix filter?
A: Yes. The Helix MagLock version attaches magnetically to a Helix Base Plate fitted to your lens. Base Plates are sold separately; CEN stocks them in 67mm, 72mm, 77mm and 82mm.
Q: What comes with the CineBlack Helix MagLock filter?
A: It includes the CineBlack Helix MagLock filter and Defenders. Helix Base Plates are not included.
Q: What strength is the CineBlack mist?
A: CineBlack is a 1/2 strength black mist diffusion filter. It gives more halation and contrast diffusion than a 1/4 strength mist while still keeping shadow depth.
