“As digital imaging sensors become more and more sensitive to light they are also more susceptible to overexposure and more sensitive to infrared light,” writes Hoya. “To address these two sensor issues, Hoya developed the SOLAS line of IRND filters.”

The SOLAS filters promise to deliver neutral color balance across the spectrum of density options—ranging from just 1 stop all the way up to whopping 10.

Size and strength options:

• 0.3 (1-stop) – 49mm ~ 82mm
• 0.6 (2-stop) – 49mm ~ 82mm
• 0.9 (3-stop) – 46mm ~ 82mm
• 1.2 (4-stop) – 49mm ~ 82mm
• 1.5 (5-stop) – 49mm ~ 82mm
• 1.8 (6-stop) – 46mm ~ 82mm
• 2.7 (9-stop) – 49mm ~ 82mm
• 3.0 (10-stop) – 46mm ~ 82mm
