Kolari Vision Mist Diffusion 1/4 + 3-Stop ND Magnetic Clip-In Filter for Sony E-Mount Full Frame Cameras

Featuring an aluminum frame with small built-in magnets, the Mist Diffusion 1/4 + 3-Stop ND Magnetic Clip-In Filter for Sony E from Kolari Vision secures magnetically to the camera mount, and your lens then mounts on top. The filter sits securely between the camera and the lens. It's compatible with full frame Sony E-mount cameras. The filter material is glass. A small removal tool is included but not required. The compact tool looks like a guitar pick and is included just in case, as the filter can easily be removed by hand.
