Camera Filter Kit K&F SB9344 — Gray Polarizer + ND PL 4-in-1 (ND8, ND16, ND32, ND64) for DJI Air 3S

K&F SB9344 is a 4-in-1 gray polarizer and neutral density (ND PL) filter kit made for the DJI Air 3S. The combined circular polarizer and multi-strength ND filters allow aerial photographers and videographers to control reflections, improve contrast and color saturation, and reduce incoming light for longer exposures or lower shutter speeds. The kit provides ND8, ND16, ND32 and ND64 densities together with a rotatable polarizing element, enabling rapid adaptation to changing light and scene conditions without switching separate single-purpose filters.

Advantages

The integrated ND PL design delivers two functions in one element: polarization to reduce glare and enhance sky contrast, and neutral density to limit light for motion blur or cinematic shutter settings. Precision optics minimize image softening and maintain accurate colors while the circular polarizer is adjustable to fine-tune reflection suppression. The selection of four ND strengths covers a wide range of lighting situations from mildly bright to very bright scenes, reducing the need to carry multiple individual filters.

Suitable for

• Aerial landscape photography with DJI Air 3S
• Outdoor videography and cinematic drone footage
• Shooting over water, glass, or wet surfaces to reduce reflections
• Long-exposure sky, cloud motion, or smooth water effects from a drone

Key specifications

• Filter type: Circular polarizer combined with neutral density (ND PL)
• ND densities included: ND8, ND16, ND32, ND64
• Compatibility: Designed for DJI Air 3S camera system
• Functionality: Adjustable polarization and light reduction for exposure control
• Intended use: Aerial photography and videography in bright conditions

How to use

Attach the filter kit to the DJI Air 3S camera following the manufacturer's mounting alignment. Rotate the polarizer element while observing the monitor or live view to reduce reflections and increase sky contrast; then select the ND density that provides the desired light reduction for your exposure. Use lower ND values for mild attenuation and higher ND values (ND32, ND64) when bright sunlight requires greater shutter speed reduction. Verify framing and exposure before recording, and adjust the polarizer rotation or ND selection as lighting changes during the flight.

Usage recommendations

Use the circular polarizer primarily when shooting at angles that include sky, reflective surfaces, or haze; avoid extreme polarization at very wide angles that can produce uneven sky darkening. When planning long-exposure or cinematic shutter effects, bracket exposures on the ground first to determine the optimal ND density for your desired shutter speed, and monitor histogram and live view during flight to prevent clipping.
