72 mm Light Pollution Filter
The Freewell 72 mm Light Pollution Reduction (NV) filter is designed for night-time photography. It uses a magnetic quick-swap system for fast attachment. High-definition optical glass with double-sided multi-coating prevents colour shift. Coatings provide waterproof, dustproof, scratchproof and oilproof protection.
Astrophotographers needing fast filter changes
This filter suits photographers shooting night skies in light-polluted areas who want rapid filter swaps. It is not for users with lens threads other than 72 mm unless they use a step ring. Buyers wanting a traditional screw-on filter or a different light-pollution bandwidth should look elsewhere.
72 mm thread with magnetic quick-swap mount
The filter fits 72 mm filter threads directly and works within the Freewell Magnetic Quick Swap System. This specific mount type decides compatibility; the filter will not attach to standard threads without the magnetic base adapter. Ensure your lens or adapter matches this 72 mm magnetic interface.

Questions about this item
Should I choose the 72mm version or another size?
The filter is supplied in a 72mm diameter; select this size only if your lens has a 72mm thread or you use a 72mm step-up ring.
What does the NV designation mean when I am shooting at night?
NV stands for Light Pollution Reduction; the coating blocks the yellow-orange glow from sodium-vapour street lamps so stars and nebulae record with natural colour balance.
How does the Magnetic Quick Swap mount affect filter changes?
The magnetic ring locks the filter in place in two to three seconds without threading, and the included magnetic cap protects the glass when the filter is off.
