K&F Concept SJ51T Soft Graduated GND8 Filter 100x150mm

The K&F Concept SJ51T 100x150mm Soft Graduated GND8 Filter Kit is a professional solution for balancing exposure in high-contrast scenes. Featuring Japanese AGC optical glass with 28-layer nano coating, it delivers a smooth 3-stop light reduction with excellent image quality and full weather-resistant protection.

The K&F Concept SJ51T 100x150mm Soft Graduated GND8 Filter is designed to balance exposure between bright skies and darker foregrounds, making it ideal for landscape and architectural photography. Unlike standard ND filters, this soft-edge graduated ND filter gradually reduces light by 3 stops, ensuring a natural transition without harsh lines. Made from premium Japanese AGC optical glass, the filter offers high-definition clarity with only 12.5% light transmittance and ultra-low reflectivity of 1.5. The 28-layer nano coating provides superior resistance to water, oil, and scratches, ensuring durability in demanding outdoor conditions.

This complete kit includes a lightweight CNC-machined aviation-grade aluminum filter holder and eight adapter rings (49-82mm), allowing compatibility with a wide range of lenses. With its slim 2mm glass design and included protective case, the SJ51T filter kit is a reliable and versatile tool for photographers seeking precise exposure control and professional results.
