3. Setup

3.1 Attaching the Lens

1. Ensure both the camera and lens are powered off.
2. Remove the rear lens cap and the camera body cap.
3. Align the mounting index mark on the lens with the corresponding mark on the camera body.
4. Rotate the lens clockwise (for Nikon F-mount) until it clicks into place. Do not force the lens.

3.2 Detaching the Lens

1. Ensure the camera is powered off.
2. While pressing the lens release button on the camera body, rotate the lens counter-clockwise until it stops.
3. Remove the lens from the camera.
4. Attach the rear lens cap to the lens and the body cap to the camera to protect them from dust and damage.

3.3 Attaching the Lens Hood

The lens hood helps to block extraneous light and reduce flare. Align the lens hood with the front of the lens and twist until it locks into place. For storage, the hood can be reversed and attached to the lens.

3.4 Using the Tripod Collar

The lens includes a removable tripod collar for better balance when mounted on a tripod, especially given the lens's weight. Loosen the knob on the collar to rotate the lens for vertical or horizontal shooting, or to remove the collar entirely.

4. Operation

4.1 Autofocus (AF) and Manual Focus (MF)

The lens features a switch to select between Autofocus (AF) and Manual Focus (MF) modes. In AF mode, the Hypersonic Motor (HSM) provides fast and quiet focusing. Full-time manual focus override is available, allowing you to fine-tune focus manually even when in AF mode by simply turning the focus ring.

4.2 Optical Stabilizer (OS)

The Optical Stabilizer (OS) function helps to reduce camera shake, especially useful in low light or when shooting at longer focal lengths. The OS switch allows you to turn the stabilization ON or OFF. This lens offers two OS modes:

• Mode 1 (Normal): For general shooting, compensating for vertical and horizontal camera shake.
• Mode 2 (Panning): For tracking moving subjects horizontally, compensating only for vertical camera shake.

Note:

• Turn the OS OFF when using a tripod to prevent potential image blur.
• The OS may produce a slight sound during operation; this is normal.

4.3 Zooming

Rotate the zoom ring to adjust the focal length between 70mm and 200mm. The internal zooming mechanism ensures the lens length remains constant.

4.4 Using with APS-C Cameras

When used with APS-C (crop sensor) cameras, the effective focal length will be approximately 105-300mm (depending on the camera's crop factor). This provides an even greater telephoto reach.

4.5 Using with Teleconverters

This lens is compatible with Sigma APO teleconverters (sold separately) to further extend its focal length. Refer to the teleconverter's manual for specific attachment and usage instructions.

5. Maintenance

5.1 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 optics, along with a small amount of lens cleaning solution.
• Never use harsh chemicals or abrasive materials on the lens elements or body.

5.2 Storage

• Always attach the front and rear lens caps when not in use.
• Store the lens in a cool, dry place, away from direct sunlight and extreme temperatures.
• If storing for an extended period, consider using a desiccant to prevent mold and mildew.
