5。 トラブルシューティング

If you encounter any issues with your Sony SEL85F18 lens, refer to the following common troubleshooting tips.

レンズが焦点を合わせない:

• Ensure the AF/MF switch on the lens is set to the desired mode (AF for autofocus, MF for manual focus).
• Check your camera's focus mode settings to ensure they are compatible with the lens setting.
• Clean the lens contacts on both the lens and the camera body with a clean, dry cloth.
• カメラを再起動してください。

Images Appear Soft or Blurry:

• Verify that the lens is properly focused on your subject.
• Check your camera's shutter speed to ensure it is fast enough to prevent motion blur, especially in low light or with moving subjects.
• レンズ要素がきれいで、汚れやほこりがないことを確認します。
• If using a very wide aperture (e.g., F1.8), the depth of field will be very shallow, requiring precise focus.

レンズがカメラに認識されない:

• レンズがカメラ本体にしっかりと取り付けられ、カチッと音がして固定されていることを確認します。
• Turn the camera off, detach the lens, reattach it, and turn the camera back on.
• Check for any firmware updates for both your camera and lens.
