Hoya Solas IRND 2.7 58mm 9-Stop

overview

Neutral density filters are important for filmmakers and photographers because they allow you to precisely control the amount of light passing through the lens for greater creative control over exposure. For filmmakers, this means shutter speeds that match your frame-rate while maintaining the depth-of-field you want. For photographers, it means you can use longer exposures or achieve a shallow depth-of-field in bright sunlight.

The downside to most neutral density filters is unpredictable “color shift”. This shift is caused by low-quality materials, poor manufacturing, and ignoring the infrared band of the light spectrum. This “High Red” transmission spike results in unpredictable color shifts that can change drastically as filter density and exposure times increase.

The Hoya SOLAS IRND filters help solve these issues. The result is a filter line that maintains consistent color from 1-stop to 10-stops. Filmmakers can now switch from density-to-density as the light changes without fear of a color grading nightmare. Photographers can use a 10-stop filter or even stack filters for 20+ stops and have no color shifts.

The filter is mounted into a lightweight, precision-milled aluminum frame. It includes front filter threads so you can attach additional filters or a protective lens cap.

The Solas Neutral Density filter is helpful when:

• You need to maintain exposure control by varying the amount of light entering the camera
• The dynamic range of light is too much for your camera lens to expose accurately (bright whites and dark shadows)
• Creating movement in waterfalls, rivers, and waves
• Creating motion blur of moving vehicles, trains, cars, and people
• “Panning” effect when subject maintains sharp focus while background is blurred with camera movement
