Product Overview

The Sigma 150-500mm f/5-6.3 AF APO DG OS HSM Telephoto Zoom Lens is engineered for Nikon Digital SLR Cameras, providing an extensive telephoto zoom range up to 500mm. This lens is particularly suited for capturing distant subjects in sports, wildlife, and landscape photography. It integrates Sigma's Optical Stabilizer (OS) technology to minimize camera shake during handheld shooting and a Hyper Sonic Motor (HSM) for rapid and quiet autofocus performance. The optical design includes three Special Low Dispersion (SLD) glass elements to effectively correct chromatic aberrations, while a super multi-layer coating is applied to reduce flare and ghosting, ensuring high image quality across the entire zoom range. A rear focus system is employed to maintain consistent image quality throughout the focusing process. A removable tripod socket (TS-31) is included for stable mounting on tripods or monopods.

Using the Tripod Collar (TS-31):

The included removable tripod collar is designed to provide balanced support when mounting the lens on a tripod or monopod, which is particularly beneficial given the lens's size and weight. To attach the collar, loosen the locking knob, slide the collar onto the lens barrel, and then tighten the knob firmly. The collar can be rotated to switch between horizontal and vertical shooting orientations by loosening the knob, rotating the lens, and re-tightening.

Operating Instructions

Focus Mode Switch:

Locate the AF/M switch on the side of the lens barrel. This switch controls the focusing mode:

• AF (Autofocus): Select this mode for automatic focusing. The Hyper Sonic Motor (HSM) ensures fast and quiet autofocus operation.
• M (Manual Focus): Select this mode for manual focusing. Rotate the focus ring to adjust the focus. Note that full-time manual override is available even when the lens is set to AF mode; simply rotate the focus ring to make fine adjustments.

Optical Stabilizer (OS) Switch:

The OS switch activates the Optical Stabilizer function, which helps to compensate for camera shake, particularly useful at longer focal lengths or slower shutter speeds:

• OFF: The Optical Stabilizer function is disabled.
• ON (Mode 1): Provides general stabilization for all directions of camera movement.
• ON (Mode 2): Optimized stabilization for panning shots, where the camera is moved horizontally to follow a moving subject.

Important: When using a tripod or monopod, it is generally recommended to turn the OS function OFF to prevent potential interference with stability and ensure optimal image sharpness.

Zooming:

To adjust the focal length, rotate the zoom ring on the lens barrel. The lens allows for continuous adjustment between 150mm and 500mm. The lens barrel will extend as you zoom towards the 500mm telephoto end. A zoom lock switch is provided at the 150mm mark to prevent the lens from extending unintentionally (lens creep) during transport or when pointing the camera downwards.

Lens Hood:

The included lens hood is designed to block extraneous light from entering the lens, thereby reducing flare and ghosting in your images. It also offers a degree of physical protection to the front lens element. To attach it, align the marks on the hood and the lens, then twist until it locks into place. For convenient storage, the hood can be reversed and mounted onto the lens barrel.

Maintenance

Cleaning the Lens:

• Use a soft, lint-free cloth or a specialized lens brush to gently remove dust and loose particles from the lens surfaces.
• For smudges, fingerprints, or more stubborn dirt, apply a small amount of specialized lens cleaning solution to a clean microfiber cloth. Never apply cleaning solution directly to the lens surface.
• Avoid touching the lens elements with your fingers, as oils can leave residues.
• Do not use organic solvents such as paint thinner, benzene, or alcohol-based cleaners, as these can damage the lens coatings.

Storage:

• Always attach the front and rear lens caps when the lens is not in use to protect the optical elements.
• Store the lens in a cool, dry place, away from direct sunlight, high temperatures, and excessive humidity.
• If storing the lens for an extended period, it is recommended to place it in the provided lens case for added protection.
• Avoid storing the lens near mothballs or other chemicals that may emit volatile gases, as these can cause damage to the lens or its coatings.
