3. Ракување со објективот

3.1 Фокусирање

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

  • Автоматски фокус (AF): Set the AF/MF switch on your camera body to 'AF'. The lens will automatically focus when the shutter button is half-pressed.
  • Рачен фокус (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 Зумирање

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 Користење на филтри

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. Одржување

4.1 Чистење на објективот

  • Користете четка за дување за да отстраните прашина и лабави честички од површините на леќите.
  • For smudges or fingerprints, apply a small amount of lens cleaning solution to a clean microfiber cloth and gently wipe the lens in a circular motion from the center outwards.
  • Никогаш не користете абразивни материјали или груби хемикалии.

4.2 Складирање

  • Секогаш прикачувајте ги предните и задните капачиња за објективот кога објективот не е во употреба.
  • Чувајте го објективот на ладно и суво место, подалеку од директна сончева светлина и екстремни температури.
  • Доколку складирате подолг период, размислете за употреба на средство за одвлажнување за да спречите раст на мувла.

4.3 Мерки на претпазливост при ракување

  • Avoid exposing the lens to water or excessive humidity.
  • Do not drop or subject the lens to strong impacts.
  • Do not attempt to disassemble the lens, as this will void the warranty.

5 Смена на проблеми

5.1 Автофокусот не работи

  • Check if the AF/MF switch on your camera body is set to 'AF'.
  • Ensure there is sufficient light and contrast in the scene for the autofocus system to operate effectively.
  • Clean the electrical contacts on both the lens and the camera body with a clean, dry cloth.

5.2 Image Quality Issues (e.g., blurry images)

  • Проверете дали објективот е безбедно прицврстен на телото на фотоапаратот.
  • Check your camera's shutter speed and aperture settings. A slow shutter speed can cause motion blur, and an incorrect aperture can lead to out-of-focus areas.
  • Ensure the lens elements are clean and free from smudges or dust.
  • If using manual focus, confirm that the subject is sharply focused.

5.3 Lens Not Recognized by Camera

  • Remove the lens and reattach it, ensuring it clicks firmly into place.
  • Clean the electrical contacts on both the lens and the camera body.
  • Check your camera's firmware for updates, and ensure it is compatible with the lens.
