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: What lens size does the PolarPro Helix Base Plate 72mm fit?
A: It threads onto lenses with a 72mm filter thread. The thread size is usually printed on the front of the lens or inside the lens cap, shown as ø72.
Q: Do I need a base plate to use Helix MagLock filters?
A: Yes. The base plate is the magnetic mounting point that Helix filters attach to. Thread it on once and you can swap Helix filters on and off without threading.
Q: What's in the box?
A: The Helix Base Plate 72mm and a Defender Cap.
