2.2 Að fjarlægja linsuna
- Gakktu úr skugga um að slökkt sé á myndavélinni.
- Á meðan þú ýtir á losunarhnappinn fyrir linsuna á myndavélinni skaltu snúa linsunni rangsælis þar til hún stöðvast.
- Fjarlægðu linsuna varlega úr myndavélarhúsinu.

3.1 Aðdráttur
To change the focal length, rotate the zoom ring on the lens barrel. The focal length markings (28mm, 35mm, 50mm, 70mm, 100mm, 135mm) are indicated on the ring. Rotate towards 28mm for a wider angle of view and towards 135mm for a telephoto perspective.
3.2 Fókus
This lens features both autofocus (AF) and manual focus (MF) capabilities. The Internal Focusing (IF) system ensures that the front of the lens does not rotate during focusing, which is beneficial when using polarizing filters.
- Sjálfvirk fókus (AF): Set the AF/MF switch on the lens (if present) or camera body to 'AF'. The camera will automatically focus when the shutter button is half-pressed.
- Handvirk fókus (MF): Set the AF/MF switch to 'MF'. Rotate the focus ring on the lens barrel until the subject appears sharp in the viewfinnandi.
3.3 Makróvirkni
The lens offers a macro function for close-up photography. To engage the macro mode, typically you would zoom to the telephoto end (135mm) and then activate the macro switch or ring if available on the lens. Refer to your camera's manual for specific settings related to macro photography.
3.4 Ljósopsstýring
The aperture (f/3.8-5.6) is controlled electronically by the camera body. Select your desired aperture setting through your camera's controls. The lens will communicate with the camera to set the appropriate aperture value.
4. Viðhald
4.1 Þrif á linsunni
- Linsuþættir: Use a lens blower brush to remove dust. For smudges or fingerprints, use a clean, soft lens cloth and a small amount of lens cleaning fluid. Apply fluid to the cloth, not directly to the lens. Wipe gently in a circular motion from the center outwards.
- Linsuhús: Wipe the lens body with a soft, dry cloth. Do not use organic solvents like paint thinner or benzene.
4.2 Geymsla
- Store the lens with front and rear caps attached in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid storing the lens in areas with high humidity to prevent mold growth. If storing for extended periods, consider using a desiccant.
4.3 Meðhöndlunarráðstafanir
- Forðist að láta linsuna detta eða verða fyrir hörðum höggum.
- Do not leave the lens in direct sunlight for prolonged periods, as this can damage internal components.
- Haldið linsunni frá sterkum segulsviðum.
