Aurora Aperture Mount Format (AMF) is a drop-in filter system for mirrorless cameras that makes using filters simple. 

Filter systems for lenses can be a headache. Step-up rings, step-down rings, swapping lenses, swapping adapters, depending on the needs of your lens collection. While mirrorless cameras make using your favorite lenses easy, having a collection of filters in the right diameter can get annoying.

Aurora Aperture addresses this common problem of mirrorless shooters with their drop-in filter system. 

The AMF system is paired to the lens adapter, not the lens. The filters drop directly into the lens adapter. The filters are small, lightweight, and you only need one set for all of the lenses you use with that lens adapter. 

The best part? The filters are extraordinarily affordable. 

Available via Aurora Aperture's Kickstarter campaign, for the cost of a Canon drop-in filter mount and filter, you can purchase 8 AMF filters. A single unit is available for $44.

The article didn't get into this question. Just wondering if anyone else like me, said "hey, cool product, but there are some issues related to flange to focal distance when adding an additional piece of glass between the lens and the sensor"?

While this is better than just having to screw the filters on the lens, this is still not really ideal If you are running and gunning.
