- FAQ
Getting Started with Helix:
Can I use Helix with other filter systems/thread plates/etc.?
The Helix MagLock system is not interchangeable with other PolarPro (or 3rd party) systems or products.
Do Helix filters cause vignetting issues?
All Helix filters avoid vignetting down to 16mm focal lengths with a single filter. When stacking two filters, vignetting starts to occur below 19mm focal lengths.
What size lens threads does Helix fit?
Helix filters connect to your lens(s) via Base Plates, which are available in 67mm, 72mm, 77mm, and 82mm thread sizes.
Can I stack multiple Helix filters?
Yes, Helix filters can be stacked and combined to create desired effects. However, vignetting will occur at focal lengths below ~20mm when stacking filters.
