Podrobný popis

The K&F Concept SJ51T 100×150mm 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 100×150×2mm 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.
