One Set of Filters for Every Lens

Aurora Aperture Adapter Mount Format Filter (AMF) filter is a revolutionary filter format that works for all DSLR lenses on popular mirrorless mount adapters. You will only need one set of filters for all your adapted lenses, no more multiple sets of filters or step-up rings, or complicated and bulky square filter systems.

The AMF drop-in filters work extremely well with ultra wide-angle lenses, especially those that have a protruding front element and are without front filter threads. Those types of lenses require a bulky filter adapter paired with very large filters. They are inconvenient to carry around and are unfriendly to your wallet. The AMF Filters is currently available through a kickstarter.com crowdfunding campaign.

Press Release: Aurora Aperture Introduces PowerND Family and an Industry First Rear Mount Glass Filter for Canon EF 11-24mm F4L USM Posted on April 21, 2017 Irvine, California, April 21, 2017 – Aurora Aperture Inc., a Southern California startup, today has introduced the PowerND family of high quality fixed neutral density (ND) filters.

The PowerND family consists of three ratings of light reduction capability: ND64 (6 stops),ND4000 (12 stops), and ND65000 (16 stops). Four different formats are available: circular filters from 37mm to 95mm, 100 x 100mm square filters compatible with popular square filter adapters, 150mm circular filters with an adapter for the Nikon AF-S 14-24mm f/2.8G ED lens, and the Aurora CR format, an industry first, a rear mount glass filter for the Canon EF 11-24mm F4L USM lens.

The 6 stop filter is typically used in low light conditions such as during sunrise or sunset for sub-second shutter speed. The 12 stop filter can slow down shutter speed to minutes in dusk and dawn conditions. The 16 stop filter can do magic on a bright day, allowing photographers to expose up to several minutes or more.

The ND4000 and ND65000 have distinct advantages in having more stops than the typical ND1000 or ND32000. They allow users to avoid diffraction softening by enabling users to avoid very small aperture settings or alternatively allowing for longer exposures. In the case of the PowerND 4000 that means two more stops than the typical ND1000 and for the Power ND65000 there’s one additional stop.

“We introduced a variable ND family last year and it was embraced by photographers and videographers worldwide,” said Jinfu Chen, founder and CEO of Aurora Aperture Inc. “the fixed ND family we introduce today is much more powerful in terms of light reduction capability and offers even better optical performance, along with more formats for different camera lenses.”

A small rear mount filter using Gorilla Glass for the Canon EF 11-24mm F4L USM is an industry first. Prior to this users would have to use extremely large filters with diameters up to 186mm with a bulky front lens shade adapter. The Aurora CR format filter mounts in the rear of the lens, making it much easier to carry and lower in cost. Other Canon lenses that Aurora CR format filter can be used in* are the EF 8-15mm f/4L Fisheye, EF 11-24mm F4L USM, EF 14mm f/2.8L US, EF 15mm f/2.8 Fisheye, EF 16-35mm f/2.8L USM, and EF 17-40mm f/4L USM.

Designed in California by Aurora Aperture, the Aurora PowerND filters employ up to 128 layers of double sided nano coating** in order to achieve color accuracy and powerful light reduction capability. Hydrophobic and oleophobic coating is applied to filter surface with PFPE coating. The end result is that water droplet on the filter surface can maintain a static contact angle of 110 degrees, one of the best in the industry.

Availability and Pricing

The Aurora PowerND family will be available through Kickstarter starting in April 2017 and to dealers and direct orders in August 2017. List price starts at US$42 and varies depending on filter format and size.
