About the PolarPro PM-6/9
From our tech experts at CEN
A variable neutral density filter, offering around 9 stops of adjustment, using PolarPro’s MagLock magnetic mount so it clicks on and off rather than threading, from the Peter McKinnon signature series.
Who it suits
Video shooters above all. A variable ND is what lets you hold a 180-degree shutter in changing light without stopping to swap filters, which is the difference between footage that looks cinematic and footage that looks like video.
Our tech experts advise
Variable NDs can cross-polarise at their extremes, so stay within the marked range rather than pushing to the stops. The magnetic mount is quick, but check you have the right base plate for each lens. get in touch for advice.

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.
Q: How many stops does this Helix VND cover?
A: It covers 6 to 9 stops, designed for shooting wide open apertures in extremely bright conditions. A preset stop range prevents cross polarisation.
Q: Do I need a Helix base plate?
A: Yes. The filter comes with defenders but needs a Helix base plate on your lens, which is sold separately.
Q: Will this filter vignette on wide lenses?
A: There is no vignetting down to 17mm with one filter fitted.
