Adjustable lens filter Sunnylife A3S-FI925 CPL + ND8/ND16 (variable circular polariser and neutral density)

The Sunnylife A3S-FI925CPL adjustable lens filter set for AIR 3S includes three filters: CPL, ND8 and ND16. Designed to improve image quality and control exposure, the set provides tools for reducing reflections, enhancing color saturation and managing light in various shooting conditions. Lightweight aluminum frames and optical glass elements keep total weight low for stable flight performance.

Advantages

The CPL filter removes glare from water, glass and other reflective surfaces, increasing clarity and contrast while enhancing sky and color tones. ND8 and ND16 filters reduce incoming light by 3 and 4 stops respectively, allowing correct exposure in bright conditions and enabling longer shutter times. The CPL is adjustable to set the desired polarization angle. All three filters are manufactured with precision and housed in protective foam packaging for safe storage and transport.

How to use

Select ND8 for moderately bright conditions and ND16 for very bright sunlight to avoid overexposure and allow longer exposure times. Keep filters clean and install them securely to avoid vignetting or movement during flight.

Recommendations

Store filters in the supplied foam-padded case when not in use and handle optical glass surfaces with a soft microfiber cloth. For best results, check exposure on a test shot after installing a filter and adjust camera settings as needed.
