Promaster 8693 HGX Prime IRND 5 級 100mm x 100mm 32 濾鏡

Finally, a 100mm square ND that doesn't shift my colors noticeably. The glass is clear, and the five stops let me open up my aperture in bright light without overexposing.

Getting sharp 3-minute exposures at f/11 without any color shift is exactly what I needed for my landscape work. The 100mm size slides smoothly into my holder and the glass feels substantial.

Shot a full afternoon of long exposures and the color cast is barely noticeable compared to my old filters. The 5-stop reduction let me keep my aperture wide open even in bright sunlight, which made for much cleaner images.
