3. Setup Guide
3.1 Attaching Adapter Rings
Select the appropriate adapter ring (Φ67/72/77/82-95mm) that matches your lens's filter thread size. Screw the adapter ring onto the front of your camera lens until secure. The matte box will then attach to this adapter ring.

3.2 Mounting the Matte Box
Align the matte box with the installed adapter ring on your lens. Gently push the matte box onto the adapter ring until it clicks into place. Ensure it is firmly seated to prevent movement during operation.

3.3 Installing Filter Trays
The kit includes two 4 x 5.65" filter trays. To install, slide your desired square filters into the trays. Then, slide the loaded filter trays into the designated slots on the matte box. The quick-release design allows for fast filter changes.

3.4 Attaching and Adjusting Flags
Attach the top flag and side flags to their respective mounting points on the matte box. These flags are adjustable (0-180° for top and side flags, up to 40° for side flags when fully open) to block stray light from various angles. Position them to effectively eliminate lens flares without obstructing the lens's field of view.

4. Operating Instructions
4.1 Filter Management
The matte box supports two 4 x 5.65" square filters (4mm thick) simultaneously. It also accommodates circular filters up to Φ92.5mm in diameter when used with the appropriate adapter ring. The quick-release mechanism allows for rapid insertion and removal of filter trays, facilitating efficient workflow during shoots.

4.2 Anti-Glare Adjustment
Adjust the top and side flags as needed to block unwanted light sources. For optimal performance, position the flags just outside the camera's field of view to prevent vignetting while maximizing glare reduction. The carbon fiber construction ensures lightweight handling and durability.

5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the matte box and flags. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid abrasive cleaners or solvents.
- Filter Care: Handle filters by their edges to avoid fingerprints. Use a lens cleaning solution and microfiber cloth specifically designed for optical surfaces.
- Storage: Store the matte box and its components in the provided storage bag or a protective case when not in use to prevent dust accumulation and scratches.
- Inspection: Periodically check all screws and connections to ensure they are secure.
6. Troubleshooting
- Difficulty Inserting Filter Trays: Ensure filters are correctly seated within the trays and that the trays are aligned with the matte box slots. Apply gentle, even pressure. Avoid forcing the trays.
- Vignetting (Dark Corners):
- Check that the flags are not extended too far into the lens's field of view.
- Ensure the matte box is correctly mounted and not misaligned.
- Verify that the lens focal length is compatible with the matte box's design (e.g., 16mm vignetting-free performance is specified).
- Matte Box Feels Loose: Ensure the matte box is fully pushed onto the adapter ring and that the adapter ring is securely tightened to the lens.
