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

עפענונג קאָנטראָל

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.

רייניקונג די לענס

• 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.
• Never use abrasive materials or harsh chemicals.

טראָובלעשאָאָטינג

אַוטאָפאָקוס ישוז

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

• Firmware דערהייַנטיקן: 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.
• פאָקוס קאַלאַבריישאַן: 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.
• לייטינג טנאָים: Autofocus performance can be affected by very low light or subjects with low contrast. Switch to manual focus if necessary.

בילד קוואַליטי קאַנסערנז

If images appear soft or lack expected sharpness:

• Check Focus: Ensure your subject is in sharp focus. In manual focus, verify using Live View מאַגנאַפאַקיישאַן.
• עפענונג: 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.
