6. Operating Instructions
6.1. Manual Focus
This is a manual focus lens. To achieve sharp images:
- Set your camera to manual focus (MF) mode.
- Look through the viewfinder or use the camera's LCD screen.
- Rotate the focus ring on the lens until your subject appears sharp. Utilize your camera's focus peaking or magnification assist features for precise focusing, especially at 1:1 magnification.
- The lens features a focus distance scale and depth of field scales to assist with focusing.
6.2. Aperture Control
The aperture is controlled via the aperture ring on the lens:
- Rotate the aperture ring to select your desired f-stop (from F2.8 to F16).
- A wider aperture (smaller f-number like F2.8) allows more light and creates a shallower depth of field (more background blur).
- A narrower aperture (larger f-number like F16) allows less light and creates a deeper depth of field (more of the scene in focus).
6.3. Exposure Settings
Since this is a manual lens, you will need to adjust your camera's shutter speed and ISO settings to achieve correct exposure based on your chosen aperture. Many mirrorless cameras can display a live preview of exposure, or you can use the camera's light meter.

7. Maintenance and Care
- Cleaning Lens Elements: Use a lens blower brush to remove dust. For smudges, use a clean microfiber cloth and a small amount of lens cleaning solution. Wipe gently in a circular motion from the center outwards.
- Cleaning Lens Body: Use a soft, dry cloth to wipe the lens body. Avoid harsh chemicals.
- Storage: Store the lens in a cool, dry place away from direct sunlight and extreme temperatures. Use front and rear caps to protect the elements.
- Avoid Moisture: Do not expose the lens to rain or high humidity. If it gets wet, dry it immediately with a soft cloth.
8. Troubleshooting
- Camera not recognizing lens: Ensure the lens is securely mounted. Check camera settings to allow shooting without a lens (often called 'Release shutter without lens' or similar).
- Images are blurry: Verify that the camera is set to manual focus (MF). Use focus peaking or magnification assist for accurate focusing. Ensure adequate lighting and appropriate shutter speed to prevent camera shake.
- Exposure issues: Since the lens is manual, adjust shutter speed and ISO on your camera to achieve correct exposure. Use your camera's light meter as a guide.
