Varnostne informacije
- Ne glejte skozi lečo v sonce ali močne vire svetlobe, saj lahko to povzroči trajno poškodbo vida.
- Ko leče ne uporabljate, jo hranite stran od neposredne sončne svetlobe, da preprečite nevarnost požara zaradi koncentrirane svetlobe.
- Izogibajte se izpostavljanju objektiva ekstremnim temperaturam, visoki vlažnosti ali korozivnim kemikalijam.
- Handle the lens with care. Dropping or subjecting it to strong impacts can cause internal damage.
- Hraniti izven dosega otrok.

Nastavitev
Pritrditev objektiva na fotoaparat
- Prepričajte se, da sta tako fotoaparat kot objektiv izklopljena.
- Odstranite zadnji pokrovček objektiva z objektiva in pokrovček ohišja s fotoaparata.
- 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.
Pritrjevanje sončne zaslonke
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.
Upravljanje objektiva
Osredotočanje
- Samodejno ostrenje (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.
- Ročno ostrenje (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.
Povečava
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.
Nastavitve zaslonke
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.
Vzdrževanje
Čiščenje leče
- Za odstranitev prahu s površine leče uporabite puhalnik.
- 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.
- Za čiščenje leče nikoli ne uporabljajte organskih topil, kot sta razredčilo za barve ali benzen.
Shranjevanje
- Ko objektiva ne uporabljate, namestite sprednji in zadnji pokrovček.
- Lečo shranjujte na hladnem in suhem mestu, stran od neposredne sončne svetlobe in visoke vlažnosti.
- Če shranjujete dlje časa, razmislite o uporabi sušilnega sredstva, da preprečite rast plesni.
Previdnostni ukrepi pri ravnanju
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.
