About the PolarPro PM-GLDMST-1/2
From our tech experts at CEN
The PolarPro CineGold Filter Helix MagLock (PM-GLDMST-1/2) is a 1/2 strength gold mist diffusion filter that locks magnetically onto any lens fitted with a Helix Base Plate. It is designed to emulate the creamy highlights and low contrast of Kodak Portra 400 film. German-made Chroma glass with anti-reflective, anti-fingerprint and anti-scratch coatings gives 90% light transmission.
Who it suits
This filter suits videographers and photographers who want a warm, cinematic look with softened digital harshness. The 1/2 strength delivers a noticeable diffusion effect, well suited to portrait and cinematic shooting. For a subtler result, the PolarPro McKinnon 135 Series 1/4 Gold Mist offers lighter diffusion.
Our tech experts advise
The MagLock system requires a Helix Base Plate, sold separately in 67mm, 72mm, 77mm and 82mm thread sizes — check your lens thread size before ordering. The filter ships with Defenders to protect the glass between shoots. The magnetic attachment makes switching filters quick in the field. Browse the PolarPro collection to find a compatible Base Plate.

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 CineGold 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 CineGold Helix MagLock filter?
A: It includes the CineGold Helix MagLock filter and Defenders. Helix Base Plates are not included.
Q: What does the CineGold filter do to an image?
A: CineGold is a 1/2 strength gold mist diffusion filter with 90% transmission. It gives a softer image with less contrast, warmer highlights and neutral shadows, designed to emulate Kodak Portra 400 film.
