Setup

Attaching the Lens

1. Ensure both the camera and lens are clean and free of dust.
2. Remove the rear lens cap and the camera body cap.
3. Align the lens mount index mark (usually a white dot or line) on the lens with the corresponding index mark on your camera body.
4. Insert the lens into the camera mount and rotate it clockwise (for L-Mount) until it clicks into place. Do not force the lens.

Detaching the Lens

1. Turn off the camera.
2. While pressing the lens release button on the camera body, rotate the lens counter-clockwise until it stops.
3. Carefully remove the lens from the camera body.
4. Attach the front and rear lens caps to protect the lens elements.

Attaching the Lens Hood

The supplied lens hood helps to block extraneous light and reduce flare. Align the red dot on the lens hood with the red dot on the front of the lens, then twist the hood clockwise until it locks into place. To remove, twist counter-clockwise while pressing the release button on the hood.

Operation

Autofocus (AF)

Set the AF/MF switch on the lens to "AF". The lens will automatically focus when the camera's autofocus system is activated (e.g., by pressing the shutter button halfway). Refer to your camera's manual for specific autofocus settings and modes.

Manual Focus (MF)

Set the AF/MF switch on the lens to "MF". Rotate the focus ring on the lens to adjust focus manually. Use your camera's focus peaking or magnification features for precise manual focusing.

Manual Override (MO)

This lens supports Manual Override (MO), allowing you to fine-tune focus manually even when the lens is set to AF, without needing to switch to MF mode. This feature is active when the camera is set to AF-S (Single-shot AF) mode.

Aperture Control

The aperture (f-number) is controlled via your camera body. Consult your camera's instruction manual for details on setting the aperture.

Maintenance

Cleaning the Lens

• Use a blower brush to remove dust from the lens surface.
• For smudges or fingerprints, use a clean, soft microfiber cloth specifically designed for optical lenses. Breathe lightly on the lens surface before gently wiping in a circular motion from the center outwards.
• For stubborn marks, apply a small amount of lens cleaning solution to the cloth (never directly to the lens) and wipe gently.
• Do not use organic solvents such as paint thinner or benzene to clean the lens.

Storage

• When not in use, store the lens with both front and rear caps attached in a cool, dry, and well-ventilated place, away from direct sunlight and high humidity.
• Avoid storing the lens near mothballs or chemicals that may emit volatile gases.
• If storing for an extended period, it is recommended to place the lens in an airtight container with a desiccant to prevent mold growth.
