Oppsett
Feste objektivet til kameraet
- Sørg for at både kameraet og objektivet er slått av.
- Fjern det bakre objektivdekselet fra objektivet og kamerahusdekselet fra kameraet.
- Align the mounting index marks (usually a white dot or line) on the lens with the corresponding mark on the camera body.
- Insert the lens into the camera's lens mount and rotate it clockwise (for Nikon F-mount) until it clicks into place. Do not force the lens.
- To detach, press the lens release button on the camera body and rotate the lens counter-clockwise until it detaches.
Feste linsedekselet
The included lens hood helps to block extraneous light, reducing flare and ghosting. Align the mark on the lens hood with the mark on the front of the lens and rotate it clockwise until it locks securely. For storage, the lens hood can be reversed and attached to the lens.
Bruk av linsen
Fokusering
- Autofokus (AF): Set the focus mode switch on the lens (if present) or camera to AF. The Hyper Sonic Motor (HSM) provides quiet and high-speed autofocusing.
- Manuell fokus (MF): Set the focus mode switch to MF. Rotate the focus ring to achieve sharp focus. This lens also features full-time manual focus override, allowing you to fine-tune focus manually even when in AF mode by simply rotating the focusing ring.
Zoomer
Rotate the zoom ring to adjust the focal length between 50mm and 150mm. The lens features an inner zooming system, meaning the overall length of the lens does not change during zooming.
Blenderåpningsinnstillinger
This lens maintains a constant maximum aperture of F2.8 throughout its entire zoom range. This allows for consistent exposure and depth-of-field control regardless of the focal length selected. The minimum aperture is F22.
Using with Tele-Converters
This lens is compatible with Sigma 1.4x EX DG and 2x EX DG APO Tele-Converters, extending its focal length capabilities. Refer to the tele-converter's instruction manual for proper attachment and usage.
Vedlikehold
Rengjøring av linsen
- Bruk en blåsebørste for å fjerne støv fra linseoverflaten.
- For smudges or fingerprints, use a clean, soft lens cloth specifically designed for optical surfaces, along with a small amount of lens cleaning fluid. Apply the fluid to the cloth, not directly to the lens.
- Never use organic solvents like paint thinner or benzene to clean the lens.
Lagring
- When not in use, attach both front and rear lens caps.
- Store the lens in a cool, dry place, away from direct sunlight and high humidity.
- If storing for an extended period, consider using a desiccant to prevent mold growth.
Forholdsregler ved håndtering
This lens is a precision optical instrument. Avoid dropping it or subjecting it to strong vibrations or impacts. While robust, severe physical shock can affect its internal components and optical alignment.
