Maintenance
To ensure the longevity and optimal performance of your APEXEL 28X Telephoto Lens Kit, follow these maintenance guidelines:
- Lens Cleaning: Use the provided cleaning cloth to gently wipe the lens surfaces. Avoid using abrasive materials or harsh chemicals that could scratch the glass.
- Storage: Always store the lens and accessories in the provided storage bag when not in use to protect them from dust, dirt, and scratches.
- Avoid Extreme Conditions: Do not expose the lens to extreme temperatures, humidity, or direct sunlight for prolonged periods.
- Handle with Care: Avoid dropping the lens or subjecting it to strong impacts, as this can damage the optical components.
Troubleshooting
Here are some common issues and their solutions:
- Q1: Why are photos easily blurred when shooting with a high-powered lens?
Blurring is usually caused by handheld shaking, low light, or inaccurate focusing. It is recommended to fix the phone with a tripod, manually rotate the focus ring to adjust slowly until the picture is clear, and prioritize shooting in a well-lit environment. - Q2: What should I do if I always feel out of focus after installing the lens?
The depth of field of the high-magnification lens is shallow, and it is easy to lose focus with slight movement. Please make sure that the phone and the lens fit perfectly (the main camera is aligned with the center of the lens) and refer to the manual to maintain a stable shooting distance. - Q3: The lens is easy to loosen or fall off when mounted on the cell phone, how to solve it?
It may be that the size of the cell phone does not match the fixture (e.g., excessive camera protrusion, the case is too thick or the cell phone is on the small side). Please make sure the phone model is in the official compatibility list, use silicone spacers to fill the gap and tighten the fixture screws.

Addressing Black Corners in Photos

- For iPhone 13 and newer: Turn off macro controls on the camera screen and use the main camera.
- For Samsung Galaxy S22/S23 Ultra: Disable focus enhancement.
