The 67mm Universal Phone Filter Mount is the simplest way to attach any 67mm filter to almost any phone (see compatibility below) with or without a case. This precise, machine aluminum mount uses a padded thumb screw to secure the mount to your phone while enabling full mobility to place the filter anywhere you want. This maximizes compatibility, so you can add a 67mm filter to cover all the lenses on your camera phone. Unlike other mobile filter solutions that block the mic hole, it allows you to use the audio from your phone’s rear-facing microphone while filming. We achieved this by machining a speaker grill into the mount and bonding a sound-permeable membrane to allow audio to pass through. Don’t worry, though; it doesn’t let any light in. The whole mount forms a tight seal to the phone, meaning no light is allowed through the cracks for the cleanest image possible.
