• Focusing Inaccuracy: If you experience consistent front or back focusing, especially with autofocus, your camera body may require microadjustment (also known as AF Fine Tune or AF Microadjustment). Refer to your camera's instruction manual for details on how to calibrate focus for specific lenses. Manual focusing with focus magnification can also help verify focus accuracy.
• Kanta Tidak Dipasang Dengan Kekunci: Ensure the lens is correctly aligned with the camera mount's index mark and rotated until it clicks. Check for any obstructions on either the lens mount or camera mount.
• Dust or Smudges on Images: This is often due to dust on the camera sensor, not the lens. However, ensure the lens elements are clean. If the issue persists, consult your camera's manual for sensor cleaning procedures or seek professional service.
• Lens Flare: While the built-in hood helps, strong light sources directly entering the lens can still cause flare. Repositioning your shot or using your hand to shade the lens can mitigate this.
