Emily ★★★★★

Put this on my wide-angle for landscape shots, and the color saturation improvement was immediate without being artificial. The 40.5mm threads fit perfectly, and I love that it doesn't cut down on light as much as my old polarizer.

Daniel ★★★★★

The 30% light transmission makes this filter usable even in the shade, which surprised me. Mounted it on my wide-angle and the sky really pops now without any weird color cast.

David ★★★★★

The colors in my landscape shots are noticeably richer, and the 30% extra light really helps me keep my ISO lower in late afternoon. I’m impressed how much sharper the images look compared to my old polarizer.
