Lentearen funtzionamendua

Focus Mode Switch (AF/MF)

The lens features an AF/MF switch on its barrel. This switch allows you to select between autofocus (AF) and manual focus (MF) modes.

• AF (Autofokua): For automatic focusing. The Hyper Sonic Motor (HSM) provides fast and quiet operation.
• MF (Eskuzko Fokua): For manual focusing. Rotate the focus ring to adjust focus. This mode is often preferred for precise focusing in specialized applications like astrophotography.

Irekiduraren kontrola

The aperture (f/1.4 to f/16) is controlled via your camera body. A wider aperture (smaller f-number) allows more light into the lens, ideal for low-light photography and creating shallow depth of field with pleasing background blur (bokeh). A narrower aperture (larger f-number) increases depth of field, suitable for landscapes.

Astrophotography Considerations

This lens is highly regarded for astrophotography due to its wide 24mm focal length and fast f/1.4 aperture. When shooting stars or the Milky Way:

• Set the lens to MF (Manual Focus).
• Focus to infinity. It is recommended to use your camera's Live View mode and zoom in on a bright star to achieve precise focus.
• Consider using a star tracker for longer exposures to prevent star trails.

Mantentzea

Lentea garbitzea

• Use a soft, lint-free cloth or a lens brush to remove dust from the lens surface.
• For stubborn smudges, apply a small amount of lens cleaning solution to a microfiber cloth and gently wipe the lens in a circular motion.
• Ez erabili inoiz material urratzaileak edo produktu kimiko gogorrak.

Biltegiratzea

• Lentea erabiltzen ez duzunean, jarri beti aurreko eta atzeko lenteen estalkiak.
• Gorde lentea leku fresko eta lehor batean, eguzki-argitik eta muturreko tenperaturetatik babestuta.
• Denbora luzez gordetzen baduzu, kontuan hartu hezetasunik gabeko agente bat erabiltzea lizunaren hazkuntza saihesteko.

Arazoak konpontzea

Foku automatikoaren arazoak

If you experience inconsistent or inaccurate autofocus, consider the following:

• Firmware eguneratzea: Sigma periodically releases firmware updates to improve lens performance. It is highly recommended to keep your lens firmware up to date. This often requires the Sigma USB Dock (sold separately) and Sigma Optimization Pro software.
• Fokuaren kalibratzea: Some camera bodies allow for in-camera micro-adjustment of autofocus. If you have a Sigma USB Dock, you can perform more precise calibration for different focus distances.
• Argiztapen baldintzak: Autofocus performance can be affected by very low light or subjects with low contrast. Switch to manual focus if necessary.

Irudien Kalitatearen kezkak

If images appear soft or lack expected sharpness:

• Egiaztatu fokua: Ensure your subject is in sharp focus. In manual focus, verify using Live View handitze.
• Irekiera: While the lens performs well wide open, stopping down by one or two stops (e.g., from f/1.4 to f/2.0 or f/2.8) can sometimes improve corner sharpness.
• Camera Shake: Use a tripod or faster shutter speed to avoid blur from camera movement.
