5. Setup and Installation
Follow these steps to install the RC25G lens onto your compatible FPV camera:
- Preparation: Ensure your camera is powered off and disconnected from any power source. Work in a clean, dust-free environment.
- Remove Existing Lens: Carefully unscrew the existing lens from your camera. Some cameras may have a locking ring that needs to be loosened first. Keep the old lens in a safe place.
- Install RC25G Lens: Gently screw the RC25G lens into the camera's lens mount (M12*P0.5 threading). Be careful not to cross-thread.
- Initial Focus Adjustment: Screw the lens in until it is nearly seated. Power on your camera and connect it to a monitor or FPV goggles. Adjust the lens by slowly rotating it clockwise or counter-clockwise until the image on your screen is clear and in focus.
- Secure Lens: Once focus is achieved, carefully tighten the locking nut (if present on your camera) against the lens to secure its position. If your camera does not have a locking nut, ensure the lens is snug but do not overtighten.
- Check for Obstructions: Some camera models or lens protectors may cause a dark circle or vignetting with a wider lens like the RC25G. If this occurs, you may need to remove the lens protector or adjust its position.

6. Operation
Once installed, the RunCam RC25G lens operates passively with your FPV camera. Its primary function is to provide a wide-angle field of view. The main operational aspect is ensuring proper focus during installation. No further adjustments are typically required during flight.
- Focus: The lens is manually focused during installation. If your image appears blurry, re-adjust the lens by rotating it slightly until clarity is achieved.
- Field of View: The wide-angle design will capture a broader scene, which is beneficial for situational awareness in FPV flying.
7. Maintenance
Proper care will extend the lifespan and maintain the performance of your RC25G lens:
- Cleaning: Use a soft, lint-free microfiber cloth specifically designed for optics to clean the lens surface. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth (not directly to the lens). Avoid abrasive materials or harsh chemicals.
- Storage: When not in use, store the lens in a protective case or with a lens cap to prevent dust accumulation and scratches.
- Handling: Avoid touching the lens glass directly with your fingers, as oils can leave smudges.
- Environmental Protection: Protect the lens from extreme temperatures, humidity, and direct impact.
8. Troubleshooting
If you encounter issues with your RC25G lens, consider the following:
- Blurry Image: This is typically a focus issue. Re-adjust the lens by rotating it slightly while observing the camera feed until the image becomes sharp. Ensure the locking nut is not overtightened before adjustment.
- Dark Corners / Vignetting: This can occur if the lens is too long for the camera housing or if a lens protector is obstructing the view. Try removing any lens protectors or ensuring the lens is not screwed in too far, if possible, while maintaining focus.
- Lens Not Screwing In: Check the threading of both the lens and the camera mount. Ensure they are clean and free of debris. Do not force the lens, as this can damage the threads. Verify compatibility.
- Image Quality Issues (beyond focus): If the image has distortions or artifacts not related to focus, ensure the lens surface is clean and free from scratches or damage.
