3.2 Attaching the Lens Hood

The included compact dome lens hood helps to prevent stray light from entering the lens, reducing flare and ghosting, and offers additional protection to the front element.

1. Align the lens hood with the front of the lens.
2. Gently screw the lens hood onto the 43mm filter thread until it is finger-tight.

3.3 Installing Filters

The lens accepts 43mm screw-in filters. To install a filter, simply screw it onto the front filter thread of the lens. The lens hood can then be attached over the filter.

4. Operating the Lens

4.1 Manual Focus

This is a manual focus lens. To focus, rotate the focus ring until your subject appears sharp in the viewfinder or on the LCD screen. The lens features a rangefinder-style focusing tab for quick and intuitive adjustments. For precise focusing, especially with wide-angle lenses, it is highly recommended to use your camera's focus peaking or magnification assist features.

4.2 Aperture Control

The lens features a physical aperture ring with distinct clicks at 1/3 stop intervals, ranging from F2.8 to F22. Rotate the aperture ring to select your desired aperture. The selected aperture value will be communicated to the camera body.

4.3 Depth of Field

The aperture setting directly influences the depth of field. A wider aperture (smaller f-number like F2.8) will result in a shallower depth of field, blurring the background. A narrower aperture (larger f-number like F11 or F16) will result in a greater depth of field, keeping more of the scene in focus.

4.4 Exposure Control

Since this is a manual focus lens with a manual aperture ring, you will typically operate your camera in Aperture Priority (A) or Manual (M) mode. In Aperture Priority, you set the aperture on the lens, and the camera automatically selects the shutter speed. In Manual mode, you control both aperture and shutter speed.

5. Maintenance

5.1 Cleaning the Lens

• Lens Elements: Use a soft lens brush or a blower to remove dust. For smudges or fingerprints, use a clean microfiber lens cloth with a small amount of lens cleaning solution. Apply solution to the cloth, not directly to the lens.
• Lens Body: Wipe the lens barrel with a soft, dry cloth. Do not use harsh chemicals or solvents.

5.2 Storage

• Always attach the front and rear lens caps when the lens is not in use.
• Store the lens in a cool, dry place, away from direct sunlight and extreme temperatures.
• Avoid storing the lens in areas with high humidity to prevent mold growth.

5.3 Water Resistance

This lens is not water resistant. Avoid exposing it to rain, splashes, or high humidity to prevent damage.

6. Troubleshooting

6.1 Lens Not Recognized by Camera

• Ensure the lens is securely mounted to the camera body. Remove and reattach the lens, ensuring it clicks into place.
• Check the electronic contacts on both the lens and camera body for any dirt or obstruction. Clean gently with a dry, lint-free cloth if necessary.
• Ensure your camera's firmware is up to date.

6.2 Difficulty Achieving Sharp Focus

• Utilize your camera's focus peaking feature, if available, to highlight in-focus areas.
• Use the magnification assist feature on your camera to zoom in on the subject for more precise manual focusing.
• Practice with the manual focus ring and focusing tab to develop muscle memory for quick adjustments.
