ProMaster adds variable neutral filters to HGX Prime collection

ProMaster announces new variable neutral density filters that join the HGX Prime professional collection with a 1.3 to 8 stop density range, which is achieved with color-corrected polarizing films that are applied using a unique, proprietary process.

Each filter is manufactured using ultra-hardened, scratch-resistant optical glass that is individually ground, polished, and coated with 36 layers of anti-reflective multi-coatings. Like all ProMaster HGX Prime filters, these Variable NDs feature a Repellamax II anti-static barrier that resists dust, dirt, oil, water, and fingerprints.

Mechanical hard stops at each end of the filter’s density range prevent photographers from going outside the minimum/ maximum useable density. For easier, repeatable control over density settings, the filter ring is visually demarcated with white lines at each full density stop—from 1.3 (minimum) to 8 (maximum.) While all VND filters are prone to cross-polarization at higher densities, the X on the ring of these filters shows you where you might start to see an X-shaped dark area in your image when using a wide-angle lens.

Installed on each filter is a small, removable, knurled knob allowing for fast, precise adjustments to the filter. Just take hold of this Tactile Control Knob to rotate to the desired density. The outer threads of these filters are the same size as the mounting thread; allowing the lens cap to be attached while the filter is installed, and also eliminating the need for steeping rings when mounting other accessories.

Each filter is packaged in an environmentally economical, minimalist container that can also be used for storing the filter when not in use. Inside the packaging is a label that directs photographers to ProMaster’s new filter microsite: filters.promaster.com. There, they will find instructions about how to use their new VND filter, as well as detailed explanations about cross-polarization.

Designed in the United States and manufactured in Japan, ProMaster HGX Prime Variable Neutral Density Filters are available in nine sizes—from 49mm to 82mm—with retail prices starting at $119.95. A complete list of pricing, specifications, and accessories can be found at filters.promaster.com.
