Olivia ★★★★★

I’ve been using this IR720 on my modified camera and the steep cut-off really makes a difference—no more muddy false-color from visible light leaking in. The 1.5mm fused quartz glass feels solid and didn’t mess up my focus calibration. Exactly what I needed for clean infrared landscapes.

Eva K. ★★★★★

The fused quartz glass on this IR720 is noticeably thinner than the cheap filters I've used before, which makes it much easier to achieve sharp focus. It blocks visible light completely, giving me exactly the deep black look I want for infrared landscapes.

Michael ★★★★★

This filter’s steep cut-off at 720nm really cleans up infrared shots without any visible light leakage. The fused quartz glass feels solid, and the 1.5mm thickness fits my adapter perfectly.
