5. Setup Instructions
5.1. Preparing Your Camera for Manual Lens Use
Since this is a fully manual lens, your camera needs to be configured to operate without detecting an electronic connection to the lens. Follow these steps:
- Turn off your camera.
- Mount the Meike 8mm f/3.5 lens onto your Canon EF-Mount camera body. Align the red dots on the lens and camera body, then twist until it clicks into place.
- Turn on your camera.
- Navigate to your camera's CUSTOM FUNCTIONS menu.
- Locate and enable the "Release shutter w/o lens" option. This setting allows the camera to take photos even when no electronic lens is detected.
- Set your camera to Manual (M) mode for full control over exposure settings.
Note: No official seller videos demonstrating this setup were provided in the product data.
6. Operating Instructions
6.1. Manual Focus
To achieve sharp images, you must manually adjust the focus ring on the lens. Use your camera's Live View mode and zoom function to precisely set the focus. The focus ring is typically the wider ring closer to the camera body.

6.2. Aperture Control
The aperture (f-stop) controls the amount of light entering the lens and the depth of field. Adjust the aperture ring (the narrower ring closer to the front of the lens) to your desired setting. The lens offers an aperture range from f/3.5 (wide open) to f/22 (most closed). Smaller f-numbers (e.g., f/3.5) result in a shallower depth of field and more light, while larger f-numbers (e.g., f/22) provide a greater depth of field and less light.

6.3. Fisheye Effect and Field of View
This lens provides a distinct fisheye perspective, characterized by its ultra-wide 200° diagonal field of view and barrel distortion. This effect is ideal for creative photography, capturing expansive landscapes, architectural shots, or unique portraits. Experiment with different angles and distances to achieve desired results. The lens hood is removable, allowing for even wider views if desired, though it may increase the risk of flare.
Note: No official seller videos demonstrating the fisheye effect were provided in the product data.
7. Maintenance and Care
- Cleaning: Use the provided lens cloth or a soft, lint-free microfiber cloth to gently wipe dust and smudges from the lens elements. For stubborn marks, use a specialized lens cleaning solution applied to the cloth, not directly to the lens.
- Storage: Always attach both front and rear lens caps when the lens is not in use. Store the lens in its bag or a dry, cool place away from direct sunlight and extreme temperatures.
- Handling: Avoid touching the glass elements directly with your fingers. Handle the lens by its barrel.
- Moisture: Protect the lens from moisture and rain. If it gets wet, wipe it dry immediately.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Camera not taking pictures with lens attached. | "Release shutter w/o lens" option is not enabled. | Go to your camera's CUSTOM FUNCTIONS and enable "Release shutter w/o lens". Ensure camera is in Manual (M) mode. |
| Images are blurry. | Incorrect manual focus. | Adjust the focus ring carefully. Use Live View and zoom in on your subject for precise focusing. |
| Images are too dark/bright. | Incorrect aperture or exposure settings. | Adjust the aperture ring on the lens and/or your camera's ISO and shutter speed settings in Manual (M) mode. |
| Black borders/vignetting on full-frame camera. | This lens is designed for APS-C sensors. | This is expected behavior for full-frame cameras. The lens is optimized for APS-C. |
| Lens hood visible in images. | Lens hood is not correctly positioned or is being used on a full-frame camera where it might intrude into the wider field of view. | Ensure the lens hood is properly attached. If using on a full-frame camera, consider removing the lens hood if it causes vignetting. |
