Overview

PowerXND-II 128 covers 1 to 7 stops, 6 elements and 2 groups, PFPE surface repelling coating, Designed in California by Aurora Aperture

Description

With unparalleled light reduction capability and image quality, the Aurora-Aperture PowerXND-II 128 67mm Variable Neutral Density Filter can be used in a wide variety of photographic applications as well as in videographic applications. The Mark II filter family takes the original PowerXND 2000 filters to the next level: Incorporating advancements developed from our core filter technologies.

Seamless Full Coverage
The PowerXND-II 128 is a 1-7 stop variable Neutral Density filter. Users can control light reduction from 1 to 7 stops, making them highly versatile tools for general photography and videography applications.

Usability Features
A direct reading scale correlates to light reduction capability so users can quickly dial-in the filter to the desired value. In addition a detachable lever for the 52mm and larger sizes of the PowerXND-II family is a standard feature that can be optionally used to assist in turning the filter.

We’ve made the knurling of the rotating ring more aggressive and added knurling to the fixed ring to improve grip when attaching and detaching the filter.

The PowerXND-II filter family maintains a slim profile to minimize vignetting on wide angle lenses. With a depth of only 6.0mm it is the thinnest among commercially available variable ND filters.

Optical Quality
The filter consists of two groups of optical glass and a thin film element. Using a proprietary bonding and polishing technique, we are able to achieve optical performance close to fixed ND filters which only have a single glass element.

Schott B270 glass and high quality polarization film from Nitto Denko are used to build the PowerXND-II. Combined with a proprietary post-bonding polishing process the filters are able to meet high resolution demands of 4k/8k video and the high pixel density of modern day camera sensors.

Multilayer nano coatings are utilized for light reduction, thus minimizing color shift. The PowerXND-II features high color accuracy on par with the benchmark of fixed ND filters such as our PowerND filters.

Lastly, a PFPE based nano coating is applied to the filter surfaces, ensuring the protection of the filter surfaces against water, oil, dust and dirt. This coating allows for easier cleaning of the filter as substances do not easily adhere and are easily removed. The PFPE based nano coating has a 110 degree static contact angle, one of the best in the industry.

Precision and Durability
The Aurora PowerXND filter frames are built from aerospace grade aluminium with computer numerical control lathes (CNC) for high mechanical precision and accuracy. They are anodized black for corrosion protection. Extended temperature range lubricant is applied in the assembly process so the filter ring will have smooth and well dampened rotation handling for all weather applications.
