ND8 Filter (0.67g): The ND8 Spark filter reduces the camera's shutter speed by 3-stops. The purpose of a ND filter is to slow shutter speed and give your video a smooth, cinematic look. Generally, you will use the ND8 on cloudy to partly cloudy days for best results.
ND16 Filter (0.67g): The ND16 Spark filter reduces the camera's shutter speed by 4-stops. With this filter you will get the best results on partly cloudy to sunny days. The ND16 will slow the DJI Spark’s shutter speed to give your videos a smooth, cinematic look.
ND32 Filter (0.67g): The ND32 Spark filter reduces the camera's shutter speed by 5-stops. Use the ND32 on very bright sunny days for best results. The ND32 will slow the DJI Spark’s shutter speed to give your videos a smooth, cinematic look.
Why Use A Neutral Density Filter?
The primary purpose of a ND filter is to reduce camera shutter speed. The 180-degree rule of shutter is a standard in motion pictures and cinema. This principle states that shutter speed should be double the frame rate to get each frame to blend together in order to create a smooth, cinematic look and feeling. If you are shooting in 4K at 30 frames per second, you want your shutter speed to be near 1/60th. To achieve a 1/60th shutter speed outdoors, typically you will need a ND filter. You will use different strengths of ND filters for different lighting conditions. Generally, the brighter it is outside, the stronger the ND filter you will need. To summarize, ND filters help lower shutter speed to capture smooth, cinematic content.
Are Our Filters Safe To Use With The Gimbal?
We put all our filters through a variety of gimbal load tests. All our DJI Spark filters are below the maximum weight threshold established with the DJI Spark. We fully guarantee filter compatibility with the DJI Spark camera and that it will have no negative effects on your gimbal. PolarPro has been making filters for gimbals and drones for 4 years. Our brand is very familiar with what these cameras and gimbals can and can’t handle. We guarantee you'll be satisfied with our new Spark filters.
What is the difference between the Cinema Series and Standard Filters?
The Cinema Series Filters for the DJI Spark feature a production level glass with a lower refractive index, leading to better image quality. Additionally the Cinema Series Glass is multi-coated with AR coatings to reduce lens flaring.
