Aurora Aperture Adapter Mount Format Filters

Aurora Aperture Adapter Mount Format Filters

Aurora Aperture – an American company specialized in making quality optical filters – has just launched its new Kickstarter campaign for the Aurora Aperture adapter mount format (AMF) filters. Several filters like UV/ND/GND/LPR are available, and they only work with mirrorless cameras using a lens mount adapter. Let’s take a closer look at it!

One Mount One Filter

Last year, Aurora Aperture successfully launched two products for filmmakers on Kickstarter. The first one is the PowerGXND, which is a variable graduated ND Filter. The second one is a set of two variable ND filters, the PowerXND Mark II.

This time, they are back with another set of filters that you don’t have to screw to the front of your lens. Indeed, the new Aurora Aperture adapter mount format filters go behind your glass, in your lens mount adapter.

These AMF drop-in filters only work with mirrorless cameras. They are compatible with 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. This system reminds me of the STC In-Body clip filters that we saw earlier this year.

The main advantage of this system is that you only need one set of filters per adapter instead of specific thread sizes/step-up rings for each lens. Also, because AMF drop-in filters go behind your glass, they are smaller, lighter, and cheaper.

Aurora Aperture claims that “any DSLR lens that can be mounted on the four supported mirrorless mount adapters.” It means that the AMF drop-in filters can fit ultra-wide-angle/fisheye lenses without a front filter thread.

Aurora Aperture Adapter Mount Format Filters

Currently, there are four filters available:

  • PowerUV™: UV filter to protect the camera sensor from light contamination.
  • PowerND™: ND filters to reduce the amount of light hitting the sensor. Various strengths are available, from ND4 (2 stops), up to ND65000 (16 stops).
  • PowerGND™: soft graduated neutral density (GND) filters. Available in ND3 (1.5 stops), ND6 (2.5 stops), and ND12 (3.5 stops) strengths.
  • PowerDusk™: reduce artificial light pollution. It is useful for astrophotography and cityscape photography.

The filter frame is made of aluminum. Several coatings are applied to both optical surfaces, like a nano-coating to reduce lights reflections, and a special PFPE nano-coating is used to repel water, oil, dust, and dirt.

Pricing and Availability

The project is live on Kickstarter until August 18th. Each filter costs $44, and several bundles are available. All AMF filters should start shipping in October.

As usual, please keep in mind that Kickstarter is not a shop or market place. Also, there are certain risks when backing a project, even if Aurora Aperture successfully delivered their products in the past.

What do you think of the AMF drop-in filters? Do you think they can be useful for your type of shooting? Let us know in the comments!
