3. Nastavitev

3.1 Pritrditev objektiva

1. Prepričajte se, da sta tako fotoaparat kot objektiv izklopljena.
2. Odstranite zadnji pokrovček objektiva in pokrovček ohišja fotoaparata.
3. Poravnajte oznako za namestitev na objektivu z ustrezno oznako na ohišju fotoaparata.
4. Objektiv zavrtite v smeri urinega kazalca (za bajonet Nikon F), dokler se ne zaskoči. Objektiva ne vstavljajte na silo.

3.2 Odstranitev objektiva

1. Prepričajte se, da je kamera izklopljena.
2. Medtem ko držite pritisnjen gumb za sprostitev objektiva na ohišju fotoaparata, zavrtite objektiv v nasprotni smeri urinega kazalca, dokler se ne ustavi.
3. Odstranite objektiv s fotoaparata.
4. Zadnji pokrovček objektiva namestite na objektiv, pokrovček ohišja pa na fotoaparat, da ju zaščitite pred prahom in poškodbami.

3.3 Namestitev sončne zaslonke objektiva

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 Uporaba ovratnika za stojalo

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. Delovanje

4.1 Samodejno ostrenje (AF) in ročno ostrenje (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 Optični stabilizator (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:

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

Opomba:

• 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 Zoomiranje

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. Vzdrževanje

5.1 Čiščenje leče

• Za odstranitev prahu s površine leče uporabite puhalnik.
• 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 Shranjevanje

• Vedno namestite sprednji in zadnji pokrovček objektiva, ko ju ne uporabljate.
• Lečo shranjujte na hladnem in suhem mestu, stran od neposredne sončne svetlobe in ekstremnih temperatur.
• Če shranjujete dlje časa, razmislite o uporabi sušilnega sredstva, da preprečite nastanek plesni in gliv.
