Setup

Attaching the Lens to Your Camera:

1. Ensure your camera is turned off.
2. Remove the rear lens cap from the 7Artisans 12mm F2.8 Mark II lens and the body cap from your Fujifilm FX mount camera.
3. Align the red dot on the lens with the corresponding red dot on your camera's lens mount.
4. Gently insert the lens into the camera mount and rotate it clockwise until it clicks into place. Do not force the lens.

Camera Settings for Manual Lenses:

Since this is a manual focus lens without electronic contacts, your camera needs to be configured to operate without a lens attached. This setting is typically called "Release w/o Lens" or "Shoot without Lens".

1. Turn on your camera.
2. Navigate to your camera's MENU settings.
3. Look for a setting related to SHOOTING SETTINGS or BUTTON/DIAL SETTING.
4. Find the option "Release w/o Lens" or "Shoot without Lens" and set it to ON or ENABLE. Refer to your camera's specific instruction manual for exact menu navigation.

Operating Instructions

Manual Focus:

This lens features a smooth focusing ring for precise manual control. To focus:

1. Look through your camera's viewfinder or use the LCD screen.
2. Rotate the Focusing Ring on the lens until your subject appears sharp.
3. Utilize your camera's focus peaking or magnification assist features for more accurate manual focusing.

Aperture Control:

The lens has a stepless aperture ring, allowing for smooth adjustments of the aperture (f-stop).

1. Rotate the Aperture Ring to select your desired f-stop, ranging from F2.8 to F16.
2. A wider aperture (smaller f-number like F2.8) allows more light and creates a shallower depth of field.
3. A narrower aperture (larger f-number like F16) allows less light and creates a greater depth of field.

Exposure Settings:

Since this is a manual lens, you will need to set your camera to Manual (M) or Aperture Priority (A) mode. In Aperture Priority mode, you set the aperture on the lens, and the camera will automatically select the shutter speed. In Manual mode, you control both aperture (on the lens) and shutter speed (on the camera).

Maintenance

Proper care will extend the life and performance of your lens:

• Cleaning: Use a soft, lint-free cloth to clean the lens barrel. For lens elements, use a lens brush to remove dust, then a lens cleaning solution and a microfiber cloth. Avoid touching the glass surfaces with your fingers.
• Storage: When not in use, keep the lens caps on and store the lens in a dry, dust-free environment, preferably in a lens pouch or camera bag. Avoid extreme temperatures and humidity.
• Handling: Always handle the lens carefully. Avoid dropping it or subjecting it to strong impacts.

Troubleshooting

Common Issues and Solutions:

• Camera not taking pictures: Ensure the "Release w/o Lens" or "Shoot without Lens" setting is enabled in your camera's menu.
• Images are blurry: Verify that the lens is properly focused using the manual focus ring. Utilize your camera's focus peaking or magnification assist. Check your shutter speed to avoid motion blur, especially in low light.
• Dark or overexposed images: Adjust your camera's exposure settings (ISO, shutter speed) in conjunction with the lens's aperture ring to achieve correct exposure.
• Dust on images: Clean the front and rear lens elements carefully. If dust persists, it may be on your camera's sensor, which requires professional cleaning or careful self-cleaning according to your camera's manual.
