ProMaster 37mm Variable ND - Digital HGX

ProMaster SKU: 4565 | Helix SKU: PR4565

Overview

The ProMaster Digital HGX Variable Neutral Density Filter provides light reduction of about 1.3 to 8.6 stops. The ND3 to ND400 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required.

ProMaster Digital HGX filters are the most advanced optical filters available today for digital photography featuring:

• Next Generation Digital Anti-Reflection Multi Coating – Specially formulated to minimize internal reflections created by CCD and CMOS sensors in a digital SLR.
• REPELLAMAX™ Element Resistant Coating – This exclusive ProMaster coating repels moisture, fingerprints, dust, dirt, and grime to ensure the sharpest images possible.
• Hardened Optical Glass – Ultra hardened optical glass resists surface scratching and stands up to the most intensive use.
• Low Profile Anti-Reflective Frame – Ultra thin low profile frame helps prevent vignetting on super wide digital format lenses. The satin-like smooth finish helps to minimize reflected light.
• Black Rimmed Glass – The outer rim of the filter glass is treated with a special black-ink.
