Promaster 77mm IRND16X（1.2）HGX Prime

Finally, a filter that doesn't introduce a color cast — the IR suppression makes a real difference in my long exposures. The coating repels dirt and dust nicely, saving me time cleaning between shots.

Ground and polished by hand, the glass is noticeably clearer than the cheaper filters I’ve tried before. It repels dirt and suppresses infrared light without adding any weird color cast to my landscapes.

I was a little skeptical about an IRND filter being worth the premium, but the way this one repels dirt surprised me on a dusty hike. It cut the glare without shifting the color, and the build quality feels solid. Definitely a worthy upgrade for coastal or forest shoots.
