Aurora Aperture Introduces Revolutionary Filter System For Mirrorless Mount Adapters

Aurora Aperture

Press release:


Irvine, California, July 15th, 2019 – Aurora Aperture Inc. today has introduced a revolutionary filter system, the Aurora Aperture Adapter Mount Format (AMF) filter for mirrorless mount adapters. 

The AMF filters drop into mirrorless camera mount adapters such as the Canon Mount Adapter EF-EOS R, the Nikon FTZ, the Sigma MC-11 for Sony E, and the Sigma MC-21 for the L mount.

“In 2017 we introduced a rear mount filter system for the Canon EF 11-24mm F4L USM: The Aurora CR format, an industry-first rear mount glass filter,” said Jeff Chen, founder and CEO of Aurora Aperture Inc. “The Aurora Aperture CR format filters solves the problem of needing a huge filter adapter and massive filters for lenses that have protruding front elements. Due to the recent pivot of mirrorless camera development and releases from Canon, Nikon, Panasonic, Sony, and others: We’ve invented the Adapter Mount Format for the mirrorless mount adapters which enables mirrorless camera users to use a single set of filters for all their DSLR lenses regardless of the filter thread size.”

One Mount One Filter

Designed in California, the Aurora Aperture AMF drop-in filters offer many advantages over traditional front–mounted lens filters. Since a drop-in filter goes inside a mount adapter, users only need one set of filters per adapter instead of specific thread sizes for each lens. It not only saves users from having to buy multiple sets of filters or large diameter filters – but it also means awkward to use step-up rings are no longer necessary.

The drop-in filters are very compact and lightweight, meaning that they’re easily carried. They cost much less than traditional front mount filters, especially in comparison to large filter thread sizes.

Any DSLR lens that can be mounted on the four supported mirrorless mount adapters can be used with these drop-in filters, whether the lens has a front filter thread or not. This is especially beneficial for ultra wide-angle lenses without a front filter thread which would otherwise require massive filters on a bulky adapter.
