1. Complete Camera Lens Filter KitThis lens filter kit includes all essential accessories for outdoor photography: neutral density filters ND2, ND4, ND8, CPL, UV, and FLD, a foldable rubber sun hood, a pressure lens cap, a carrying case, and a safety clip. Compatible with 40.5mm lens threads (marked 'Φ40.5' under the lens barrel), suitable for any camera model. 2. **Balanced Exposure with ND Filters**: Neutral density filters reduce light entering the camera sensor at varying intensities—ND2 by 1 stop, ND4 by 2 stops, and ND8 by 3 stops—ensuring balanced exposure in different lighting conditions. These ND filters also enable longexposure photography by slowing shutter speed. 3. **Light Control with CPL/UV Filter**: The CPL filter minimizes unwanted reflections from water, foliage, glass, and other nonmetallic surfaces. The UV filter safeguards your lens from scratches and fingerprints. 4. **FLD Fluorescent Filter**: Effectively eliminates fluorescent or 'greenish' tones for enhanced optical clarity. It delivers natural, truetolife images even in challenging indoor or outdoor lighting.
