Hoya HD MkII IRND8 (0.9) 55mm υπέρυθρο φίλτρο ουδέτερης πυκνότητας

The Hoya HD MkII IRND8 (0.9) is a professional-grade infrared neutral density filter designed for photographers and videographers who demand superior image quality and color accuracy. With a 3-stop light reduction and infrared cut capability, this filter prevents color shifts caused by IR contamination, ensuring natural-looking results even in bright conditions. The HD MkII series features chemically hardened optical glass with 16-layer anti-reflection, water-repellent, oil-repellent, and scratch-resistant coatings, making it exceptionally durable and easy to clean. The low-profile aluminum frame minimizes vignetting, and the front and rear filter threads allow stacking with other filters.

Advantages

The HD MkII optical performance delivers sharp, high-contrast images with minimal flare.
