Spectrum Filter SF -4 G with filter thread

Camera Lens Diameter: 55mm

The Spectrum Filter SF -4 G is designed to compensate for the light absorption of green water and therefore provides a smooth, well balanced light spectrum to the sensor of your camera. This greatly improves the color rendering of your images and adjust the color coordinates close to daylight for outstanding results with manual white balance.

The Spectrum Filter SF -4 G has a compensation depth of 8m. At this depth the filter makes a perfect compensation of the light absorption of the water column. The camera then sees a daylight spectrum just like shooting at the surface.

The filter works best for green water within a depth range of 6 to 20 meters. The filter has a damping equivalent to a loss of 4 stops. Normally low noise cameras that allow to shoot at ISO 1600 or higher are required when using this filter.

IMPORTANT: If you experience problems with too low light level switch to a lighter filter such as the SF -2 (loss equivalent to 2 stops). The use of a lighter filter is always the better option than using no filter at all!
