Photo filter Freewell Mini 5 Pro ND16/PL – neutral density ND16 with circular polarizer

Freewell Mini 5 Pro ND16/PL is a combined neutral density and circular polarizer filter designed for Mini 5 Pro-compatible camera lenses. The filter provides 4 stops of light reduction (ND16) to allow longer exposures or wider apertures in bright conditions while the circular polarizer reduces reflections and glare and increases color saturation. It is intended for landscape, cityscape and video work where controlled exposure and reduced reflections are required, and it attaches to the front of compatible Mini 5 Pro lenses.

Advantages

The integrated ND16 and PL functions eliminate the need to stack separate filters, keeping the optical path compact and minimizing vignetting. Four stops of light control enable motion blur during daylight and permit the use of wider apertures for shallower depth of field. The circular polarizer component improves contrast and color saturation by cutting reflections from non-metallic surfaces such as water and glass, while helping to reduce haze in distant scenes. The filter’s glass and coating choices are optimized for minimal impact on image sharpness and color neutrality.

Suitable for

• Landscape photography requiring longer exposures or enhanced sky contrast
• Cityscape and architectural shots where glare from glass and water surfaces is present
• Video capture to control exposure and achieve smoother motion in bright ambient light
• Long-exposure creative effects, such as smoothing water or showing motion in crowds

Key specifications

• Neutral density strength: 4 stops (ND16)
• Polarizer type: circular polarizer (PL)
• Effect combination: simultaneous ND and polarization
• Optical element: multi-coated glass designed to reduce reflections and maintain sharpness
• Mounting: screw-on attachment compatible with Mini 5 Pro lens front thread

How to use

Attach the filter to the front of a compatible Mini 5 Pro lens by screwing it into the lens thread until secure. Rotate the polarizer ring while observing through the viewfinder or live view to control the degree of polarization and reduce unwanted reflections; adjust until the desired contrast and color saturation are achieved. Use the ND function to select longer shutter speeds or wider apertures as required for exposure control—meter and review the image to confirm correct exposure settings. When not in use, store the filter in its protective case to prevent scratches and dust.

Usage recommendations

For best results, combine the ND16/PL with a tripod when using long exposures to avoid camera shake. Check for vignetting at wide focal lengths and, if necessary, use the filter with lenses recommended for Mini 5 Pro accessories. Clean the filter with a microfiber cloth and appropriate lens solution to maintain image quality.
