Dust and Spots on Photos: Dust or hair particles can get onto the sensor or lens, causing spots in images. This often requires regular cleaning, sometimes using an air blower or professional service. Inaccurate Colors (White Balance Issues): Photos may have an undesirable color cast (e.g., too blue or orange) if the incorrect white balance setting is used for the lighting conditions. Lens Mold or Fungus: In humid climates, moisture can get trapped, leading to mold growth on the lens elements. Storing the camera with silica gel packets in a dry place can help prevent this. Stuck Lens Filter: Filters left on for long periods can become difficult to remove. Gentle tapping or a rubber band for grip can help, but force should be avoided to prevent damage.
