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: Why use an ND filter for video?
A: An ND filter lets you keep your shutter speed at roughly double your frame rate in bright light, which produces natural motion blur instead of a harsh, choppy look.
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.
