The DJI Osmo Pocket 4P puts a 20mm-equivalent wide-angle camera and a 60mm-equivalent med-tele camera on the same compact gimbal. A useful filter system therefore has to cover both lenses without making setup unnecessarily complicated.
Haoge's filter system for the DJI Osmo Pocket 4 Pro uses a dedicated base that spans both cameras, with magnetic filters that attach over the base. Options include CPL, variable ND2–32, 1/4 Black Mist, UV, and light-pollution filters, as well as a wide-angle conversion lens. This guide explains what each option does, when to use it, and what to check before recording.
Why the Pocket 4 Pro Needs a Dual-Lens Filter Design
DJI describes the Osmo Pocket 4P as a physical dual-lens camera with a 20mm wide-angle lens and a 60mm med-tele lens. Only one camera records at a time; the device switches between them according to the selected zoom level. A filter made for this body therefore needs to sit correctly over both optical paths so the camera can switch lenses without requiring you to replace the accessory.
The Haoge system uses a locking base shaped for the Pocket 4P camera module. Once the base is fitted, compatible Haoge filters attach magnetically. The manufacturer states that the system is designed specifically for the Pocket 4 Pro and is not compatible with the standard Osmo Pocket 4 or other Pocket models. Check the exact camera name before ordering, because similar product names do not indicate the same mount.
Haoge also states that its Pocket 4P filters use HD optical glass with double-sided 28-layer coatings. This is a manufacturer specification rather than an independent laboratory result. Keep each filter clean and inspect it under a strong light before an important shoot.
## Which DJI Osmo Pocket 4 Pro Filter Should You Use?
Each filter solves a different shooting problem. The right choice depends on the scene, the reflections you want to control, and whether you want a neutral or stylized image.
### CPL: Control Reflections Outdoors
A circular polarizer is useful around water, glass, wet streets, and foliage. Rotate the filter while watching the live view to find the amount of reflection reduction you want. Its effect depends on the direction of the light and the camera angle.
Use a CPL when unwanted glare hides detail. Avoid treating maximum polarization as the default: reflections can add depth to water, windows, and product shots, and a wide sky may become uneven when polarization is especially strong. Adjust it for the shot instead of simply turning it to its limit.
### VND2–32: Manage Bright Light for Video
The variable ND2–32 filter provides approximately one to five stops of light reduction. It is intended for situations where the scene is too bright for the shutter speed and aperture choices you want. For video, that can make it easier to keep a slower shutter speed rather than allowing exposure settings to move toward a sharper, more staccato look.
Set your frame rate and preferred shutter speed first, then rotate the VND until the exposure is where you need it. Recheck the setting after changing lenses, zoom levels, or camera direction. Like any variable ND filter, its appearance can change with the angle of light and the strength selected, so review the frame for uneven density or color before recording a long take.
### 1/4 Black Mist: Soften Highlights and Contrast
A 1/4 Black Mist filter is a creative option rather than an exposure-control filter. It diffuses bright highlights, lowers apparent contrast, and can create a soft glow around practical lights. This can suit portraits, evening street scenes, interviews, and vlogs where a gentler rendering is part of the intended look.
The effect becomes more visible when a frame contains bright points against a darker background. It may be subtle in flat daylight and much stronger around lamps at night. Because diffusion is baked into the recorded image, run a short test clip before committing to it for an entire shoot.
### UV: Add a Clear Protective Layer
The UV option is the simplest choice when you want a physical layer in front of the camera lenses without deliberately adding diffusion, polarization, or neutral density. On a digital camera, its main role is physical coverage rather than correcting ultraviolet haze.
A UV filter cannot guarantee protection from an impact, and an extra glass surface can introduce reflections in demanding lighting. Keep it clean, remove it if it creates unwanted flare, and do not treat it as a substitute for careful storage or handling.
### Light-Pollution Filter: Refine Some Night Scenes
Haoge's light-pollution filter is designed to reduce some warm color casts associated with artificial urban lighting. It can be useful when city lights or certain street lamps dominate a night scene, especially when you want a cooler, more neutral starting point for editing.
A Compact Three-Filter Kit for Everyday Shooting
For creators who move between outdoor video, reflective scenes, and portraits, the Haoge three-filter kit combines:
- a CPL polarizer;
- a variable ND2–32 filter with a one-to-five-stop range;
- a 1/4 Black Mist diffusion filter;
- a magnetic base ring, microfiber cleaning cloth, and screen protector, according to the current product listing.
The three filters cover distinct jobs rather than acting as interchangeable color effects. The CPL manages reflections, the VND manages exposure, and the Black Mist changes highlight and contrast rendering. Haoge says up to two filters can be stacked on the magnetic base. If you stack filters, inspect the full frame at every zoom level for unexpected flare, color shifts, edge obstruction, or additional stress on the gimbal.
The separate Black Mist and light-pollution two-pack is more specialized for evening scenes. Other individual options—including UV and the wide-angle conversion lens—are better treated as separate tools selected for a specific need.
## How to Install the Haoge Pocket 4P Filter
Haoge provides the following installation sequence for its Pocket 4P filter base:
1. Power off the DJI Osmo Pocket 4 Pro.
2. Rotate the factory lens cover counterclockwise and remove it.
3. Insert the Haoge base at the specified angle, then rotate it clockwise to lock it in place.
4. Place the chosen magnetic filter onto the base.
5. Check that the filter sits flat and that both lens openings are clean and unobstructed.
6. Power on the camera and watch the gimbal complete its movement before recording.
Do not force the base if it does not rotate smoothly. Remove it, confirm its orientation, and check the mount for debris. Before walking away with the camera, gently verify that the magnetic filter is fully seated. When switching filters outdoors, point the camera downward where practical and store each removed filter in a clean case.
## A Simple Filter Workflow in the Field
Start with the image you want rather than the filter you own. If glare is the problem, choose the CPL and rotate it while viewing the actual scene. If the scene is too bright for your intended video settings, choose the VND and add only the density required. If the goal is softer highlights, use the Black Mist and judge the effect around the brightest parts of the frame.
After fitting a filter, check exposure, white balance, flare, and focus on the active lens. Then switch to the other focal length and check again. DJI confirms that the Pocket 4P uses one physical lens at a time, so a clean result on the wide camera does not automatically prove that the med-tele view is equally clean.
For critical footage, record a five-second test through the brightest area of the scene. Review it at normal speed to catch reflections, uneven polarization, excessive diffusion, or an unsuitable ND setting.
## Key Takeaways
- The Haoge Pocket 4P base is shaped to cover the camera's 20mm wide-angle and 60mm med-tele lenses.
- CPL, VND2–32, and 1/4 Black Mist filters solve different problems: reflections, exposure, and diffusion.
- UV and light-pollution filters are situational options rather than automatic choices for every shoot.
- Confirm that the product is labeled for **DJI Osmo Pocket 4 Pro (4P)**; the Haoge listing says it does not fit the standard Pocket 4.
- Power off before installation, keep both optical paths clean, and check the gimbal and both focal lengths after fitting a filter.
- Product-effect images in this article are manufacturer-supplied illustrations; actual results vary with lighting, angle, camera settings, and post-production.
## Frequently Asked Questions
### Do Pocket 4 Pro filters cover both lenses?
The Haoge Pocket 4P base and matching filters are designed to span both physical lenses. DJI states that the camera switches between its 20mm wide-angle and 60mm med-tele lenses rather than recording through both simultaneously.
### Is the VND2–32 filter suitable for all daylight conditions?
It provides about one to five stops of light reduction, which covers many daylight situations but not every possible scene or camera setting. Check exposure and image uniformity at the chosen strength before recording.
### Can I stack two Haoge filters?
Haoge states that the three-filter kit supports stacking up to two filters. Stacking adds more glass and weight, so check for flare, color shifts, obstruction, and normal gimbal movement each time.
### Will these filters fit the DJI Osmo Pocket 4?
According to Haoge's product listing, the Pocket 4P filter system fits the DJI Osmo Pocket 4 Pro only and is not compatible with the standard Pocket 4 or other models.
### Which filter is the best first purchase?
Choose by shooting problem. A CPL is useful for reflections, a VND helps control exposure in bright video scenes, and a Black Mist creates a softer visual style. If you regularly need all three, the combined kit is the more flexible starting point.
