Aurora Aperture introduces a next generation rear mount filter system




Irvine, California, May 15th, 2020 – Aurora Aperture Inc. today has introduced a next-generation rear mount filter system.

The new next-generation rear mount filter system supports the Canon 11-24mm F4L USM and other select Canon wide-angle lenses, Nikon AF-S 14-24mm f/2.8G, Sigma 14-24mm F2.8 DG HSM Art EF mount and Sigma 14mm F1.8 DG HSM Art EF mount, Sigma 14-24mm F2.8 DG DN Art E and L mount, and Sony 12-24mm F4 G.

“In 2017 we introduced a rear mount filter system for the Canon EF 11-24mm F4L USM: The Aurora Aperture CR format, an industry-first rear mount glass filter,” said Jeff Chen, founder, and CEO of Aurora Aperture Inc. “The next generation rear mount filter system is a major upgrade from the CR format filter system. It expands supported lenses to several other popular ultra-wide-angle lenses, at the same time adds more filter choices. More importantly, the new system features a robust magnetic quick-release mechanism. ”

Next Generation Rear Mount Filter System

The next generation rear mount filter system improves usability by using an innovative magnetic mounting system. A filter is installed to a supported lens simply by attaching the filter onto the magnetized adapter on the rear of the lens. The magnetic quick release feature greatly simplifies the filter installation, especially for photographers working in harsh outdoor environments.

Designed in California, the Aurora Aperture next generation rear mount filter system provides a simple and elegant solution for ultra-wide-angle lenses that lack a front filter thread. Users would normally have to use either low-quality gel filters in the rear of the lens or otherwise use a massive front mount filter with sizes up to 186mm mounted onto a bulky adapter.

The Aurora Aperture next generation rear mount filters are very compact and lightweight, making them much easier to carry. The filters are made from high-quality Schott D 263® T eco thin glass* with multi-layer nano-coatings for their light reduction capability, resulting in accurate color rendition and minimizing field curvature. These filters can meet the high-resolution demands of 4k/8k video, and the high pixel density of modern-day sensors.

A PFPE based nano-coating is applied to both optical surfaces, ensuring the protection of filters against water, oil, dust, and dirt. This coating allows filters to be cleaned as substances do not adhere to the filter easily and are removed with little effort. The PFPE based nano coating has a 110-degree static contact angle, one of the best in the industry.

The filter glass is protected by a high strength stainless steel frame. The filter frame makes the filter easier to handle and adds protection to the filter glass. Aerospace-grade 7051 aluminum alloy is used for the filter adapter. This material is practically twice as strong as the 6000 series aluminum alloy used in conventional lens filters.

Available Filters

PowerND™, neutral density (ND) filters of light reduction strength in :

  • ND4 (2 stops)
  • ND16 (4 stops)
  • ND64 (6 stops)
  • ND256 (8 stops)
  • ND4000 (12 stops)

PowerGND™, soft graduated neutral density (GND) filters of light reduction strength in :

  • ND3 (1.5 stops)
  • ND6 (2.5 stops)
  • ND12 (3.5 stops)

PowerDusk™, a light pollution reduction filter for astrophotography and for cityscape photography in blue hours by reducing artificial light pollution.
