3. Upravljanje objektivom

3.1 Fokusiranje

This lens features a Hyper-Sonic Motor (HSM) for fast and quiet autofocus. It also allows for full-time manual focus override.

• Autofokus (AF): Set the AF/MF switch on your camera body to 'AF'. The lens will automatically focus when the shutter button is half-pressed.
• Ručno fokusiranje (MF): Set the AF/MF switch on your camera body to 'MF'. Rotate the focus ring on the lens barrel to adjust focus manually. Even in AF mode, you can fine-tune focus by rotating the focus ring after autofocus has been achieved.

3.2 Zumiranje

To change the focal length, rotate the zoom ring on the lens barrel. The lens offers a focal range from 10mm (ultra-wide) to 20mm (wide-angle). The aperture will vary between f/4 at 10mm and f/5.6 at 20mm.

3.3 Using Filters

The lens has a filter thread at the front. Due to its internal focusing system, the front element does not rotate, making it convenient to use polarizing filters or other special effect filters. Ensure the filter size matches the lens's filter thread diameter.

4. Održavanje

4.1 Čišćenje objektiva

• Koristite četku za puhanje kako biste uklonili prašinu i rastresite čestice s površina objektiva.

• Čuvajte objektiv na hladnom i suhom mjestu, dalje od direktne sunčeve svjetlosti i ekstremnih temperatura.
