K&F Concept CPL ND Filter Kit for DJI Osmo Action - 6-Pack Push-In Fit

In this review of the K&F Concept Push-in Fit CPL ND Filter Kit the bottom line is simple: this 6-pack is aimed at action camera shooters who want cleaner highlights and controlled exposure without fiddly screw mounts. The kit includes a CPL plus ND8, ND16, ND32, ND64 and ND256, and the push-in fit is the single biggest reason to consider it because it installs quickly on DJI Osmo Action 5 and Osmo Action 4 bodies for fast on-location changes. The reviewer found the multi-coated AGC glass and reduced glare most useful for outdoor vlogging and waterside scenes.

Key Features

• 6-Pack filters: A complete set of CPL and five ND strengths covers common bright-light situations so the user can pick the right light reduction without carrying multiple brands.
• Push-in fit: The filters mount directly to compatible Osmo Action cameras for quick swaps and do not require removing the original protector, saving time on shoots.
• Light reduction and motion blur: ND8 through ND256 progressively cut exposure from about 3 to 8 stops to help achieve natural motion blur and balanced highlights in strong sunlight.
• Glare reduction and contrast: The CPL filter reduces non-metallic reflections on water and glass and increases color saturation for richer outdoor footage and landscape shots.
• AGC optical glass with nano coatings: Double-sided multi-layer coatings make the filters water repellent and scratch resistant while keeping image clarity and sharpness intact.

Who It's For

The kit is best for action camera owners who shoot outdoors, travel vloggers, and sports enthusiasts using DJI Osmo Action 5 or Osmo Action 4 who need fast filter changes and a range of ND strengths for bright conditions. The push-in design suits run-and-gun filming where speed and low fuss matter.

It is less suitable for users who prefer threaded screw filters or need a variable ND for fine continuous control; professionals who require bespoke optical specs or larger format filters should look at larger dedicated filter systems.

Pros & Cons

Pros

• Good value 6-pack provides a wide range of exposure control without adding much weight to the camera.
• Push-in mounting is fast and preserves the original protective filter for convenience on the fly.
• CPL improves color and reduces reflections, noticeably enhancing outdoor shots over clear water or glass.

Cons

• Push-in style may feel less secure to users familiar with screw-in mounts, and it offers less fine adjustment than a variable ND option.
