Focus Mode Switch (AF/MF)

Located on the side of the lens barrel (refer to Figure 3), this switch allows you to select between Autofocus (AF) and Manual Focus (MF) modes.

• AF (ഓട്ടോഫോക്കസ്): The camera automatically focuses on the subject. This mode is suitable for most general photography.
• എംഎഫ് (മാനുവൽ ഫോക്കസ്): You manually adjust the focus by rotating the focus ring. This mode is useful for precise focusing in specific situations, such as macro photography or astrophotography.

മാനുവൽ ഫോക്കസ് റിംഗ്

When in MF mode, rotate the large ring towards the front of the lens to adjust the focus. The focus distance scale, visible through a window on the lens barrel, indicates the current focus distance in both feet and meters.

Aperture (f/1.4)

This lens features a wide maximum aperture of f/1.4. This allows for:

• മികച്ച കുറഞ്ഞ വെളിച്ച പ്രകടനം: More light can enter the lens, enabling photography in dimly lit environments without excessively high ISO settings.
• ആഴം കുറഞ്ഞ ഫീൽഡ് ആഴം: Creates a blurred background (bokeh) to isolate your subject, which is ideal for portraits and artistic photography.

കുറഞ്ഞ ഫോക്കസ് ദൂരം

The lens has a minimum focus distance of 7.1 inches (approximately 18 cm), allowing for close-up shots with a wide perspective.

പരിപാലനവും പരിചരണവും

• ലെൻസ് വൃത്തിയാക്കൽ: Use a soft, lint-free cloth and a specialized lens cleaning solution to clean the front and rear elements. Avoid touching the glass surfaces with your fingers.
• പൊടിയും ഈർപ്പവും: Always keep lens caps attached when the lens is not in use. Avoid exposing the lens to excessive dust, dirt, or moisture. If the lens gets wet, wipe it dry immediately with a soft cloth.
• സംഭരണം: Store the lens in a cool, dry place, away from direct sunlight and extreme temperatures. Use a lens case for protection during transport.
• കൈകാര്യം ചെയ്യൽ: Handle the lens carefully to avoid dropping or impacting it, which can damage internal optical elements or the mounting mechanism.

ട്രബിൾഷൂട്ടിംഗ്

• ക്യാമറയ്ക്ക് ലെൻസ് തിരിച്ചറിയാൻ കഴിഞ്ഞില്ല: Ensure the lens is securely mounted and the camera is powered on. Clean the electronic contacts on both the lens and camera body with a clean, dry cloth.
• ഓട്ടോഫോക്കസ് പ്രവർത്തിക്കുന്നില്ല: Check if the lens is set to AF mode. Ensure there is sufficient light and contrast for the autofocus system to operate effectively.
• ചിത്രങ്ങൾ മങ്ങിയതാണ്: Verify that the lens is properly focused. If in AF mode, ensure the camera is focusing on the intended subject. If in MF mode, carefully adjust the focus ring. Check your camera's shutter speed to avoid motion blur.
• Dust spots on images: This may indicate dust on the camera sensor or the lens elements. Clean the lens elements as described in the Maintenance section. If the issue persists, consult your camera's manual for sensor cleaning procedures or seek professional service.
