Promaster 37mm Circular Polarizer HGX Prime

Wasn't expecting the 30% extra light transmission to make such a noticeable difference in low-light landscapes, but my shots came out way richer and clearer. Colors really popped without looking fake.

Put this on my 70-200mm for a portrait session and the extra light transmission made a real difference in the viewfinder when stopping down. Colors popped nicely even in midday sun, and reflections on glass practically vanished.

Used it on a rainy landscape shoot and the 30% extra light made a huge difference in shutter speed. Colors really popped without any weird color cast, and reflections on wet rocks vanished completely.
