Rear Clear Night Filter for Sigma 0.5-0.9 inches (14-24 mm) F2.8 DG DN Art Lens, Sony E Mount/L Mount

Landscape photographers can now enjoy a new rear lens filter that caters to their needs. This filter is designed for ultra-wide angle lenses where a traditional front-mounted filter cannot be used. The key advantage of this rear filter is that it allows the use of ND (Neutral Density) filters without the need for a large filter holder, thereby expanding the range of creative expressions available to photographers.

Specifically, this filter is a clear night filter, or a light pollution reduction filter, tailored for night sky photography. Crafted with high-quality K9 optical glass, the impact on image quality is significantly less compared to gelatin filters. The filter effectively reduces the influence of street lighting on night sky shots, enabling natural color reproduction.

Furthermore, the filter absorbs the yellow hue of sodium lamps, preserving the true colors of the night sky. This feature is particularly beneficial for astrophotography, where accurate color rendition is crucial.

The use of high-quality K9 optical glass is a key attribute of this rear lens filter. Unlike gelatin filters, it minimizes the impact on overall image quality. Additionally, the filter is equipped with a Nano coating, which not only prevents reflections and scratches but also offers a water-repellent effect, making it more durable and easier to maintain.

The ultra-wide angle lens design of this rear filter allows photographers to capture images with filters, expanding their creative possibilities. This is particularly advantageous for landscape photographers who often require the use of ND filters to achieve long exposures or control the amount of light entering the lens.

In summary, this new rear lens filter for landscape photographers offers a solution to the challenges posed by ultra-wide angle lenses, enabling the use of ND filters without the need for a bulky filter holder. With its high-quality optical glass, effective light pollution reduction, and protective Nano coating, this filter promises to enhance the creative potential of landscape photographers, especially those focused on night sky and astrophotography.
