Product Information
Full details
The Freewell Mini 4 Pro Soft Edge Gradient Filters 2-Pack is designed for DJI Mini 4 Pro users looking to achieve balanced landscape photography and videography. Its primary benefit is creating evenly exposed shots by reducing bright skies while maintaining foreground detail, preventing blown-out highlights and dark shadows. A potential caveat is the need for careful alignment to achieve the desired gradient effect. This kit includes two graduated neutral density filters, GND 0.9 (3-stop) and GND 1.2 (4-stop), featuring durable coatings for protection and a 30.5mm thread size.

FAQs
What is the main purpose of a graduated neutral density filter?
A GND filter helps to balance the exposure in a scene where there is a significant difference in brightness between the top and bottom (or sides) of the frame, such as a bright sky and a darker landscape.
What is the difference between GND 0.9 and GND 1.2?
GND 0.9 reduces light by 3 stops (allowing 1/8th the light), while GND 1.2 reduces light by 4 stops (allowing 1/16th the light). The 1.2 filter offers stronger light reduction.
Are these filters compatible with other DJI drones?
These filters are specifically designed with a 30.5mm thread size for the DJI Mini 4 Pro. Compatibility with other drones would depend on their respective lens thread sizes.
How do I clean the filters?
Use a soft microfiber cloth. For tougher spots, a small amount of lens cleaning solution can be applied to the cloth, then gently wipe the filter. Avoid using abrasive materials.
Will these filters affect the drone's flight time?
The filters are designed to be lightweight, but adding any accessory can have a minimal impact on battery life. The effect is generally negligible for short flights.
What does 'soft edge' mean for a gradient filter?
A soft edge gradient filter has a gradual transition between the clear and dark areas, making it ideal for scenes with irregular horizons, like mountains or trees, where a hard edge would be too noticeable.
Can I stack these filters?
While technically possible, stacking graduated filters is generally not recommended as it can lead to uneven lighting and potential image degradation. These filters are designed for individual use based on lighting conditions.
Troubleshooting
Filter causes noticeable vignetting
Ensure the filter is correctly seated and not cross-threaded. For wider shots, check if the filter diameter is causing obstruction.
Image appears unevenly darkened despite correct placement
Verify the filter is clean and free of smudges or debris. Ensure the gradient line is aligned with the horizon or key transition point in the scene.
Filter is difficult to screw on or off
Check for debris in the threads of both the filter and the drone's lens. Ensure you are screwing it on straight and not cross-threading. Avoid forcing the filter.
Image quality is reduced (softness, flares)
Ensure the filter is clean. Be mindful of the light source; direct sunlight on the filter can cause flares. The soft edge design is intended to minimize harsh transitions.
Pros and Cons
Pros
- Achieves balanced exposures in high-contrast scenes.
- Protects against dust, oil, and scratches.
- Provides two useful levels of light reduction for different conditions.
- Designed for seamless integration with the DJI Mini 4 Pro.
- Enhances detail in both sky and ground elements of a shot.
Cons
- Requires manual adjustment for optimal gradient placement.
- May add slight weight to the drone.
- Not suitable for situations requiring uniform light reduction across the entire frame.
Setup, Compatibility & Care
Compatibility
These filters are specifically designed for the DJI Mini 4 Pro drone, featuring a 30.5mm thread size that screws directly onto the drone's camera lens.
Setup
- Ensure your DJI Mini 4 Pro is powered off.
- Carefully align the filter's threaded side with the front of the drone's camera lens.
- Gently screw the filter clockwise onto the lens until it is securely in place. Do not overtighten.
- When attaching or removing, hold the drone's camera gimbal steady to avoid stressing the camera mechanism.
Care
- Cleaning: Use a soft, lint-free microfiber cloth to gently wipe the filter surface. For stubborn smudges, slightly dampen the cloth with lens cleaning solution. Avoid abrasive materials or harsh chemicals.
- Storage: Store the filters in their protective case when not in use to prevent scratches and dust accumulation. Handle with care to maintain the integrity of the coatings.
