2.3 Camera Compatibility and AF Engagement

This lens is compatible with Nikon F-mount cameras. For autofocus functionality, your camera body must have a built-in autofocus motor. Without an AF motor in the camera body, the lens will operate in manual focus mode only.

To enable autofocus and allow the camera to control the aperture, the aperture ring on the lens must be set to its minimum aperture (f/32) and locked in that position. Failure to do so may result in an AF error or prevent the shutter from releasing.

3. レンズの操作

3.1 フォーカシング

• オートフォーカス（AF）： When the lens aperture ring is set to f/32 and locked, and the camera body has an AF motor, the camera will control focusing. The outer ring of the lens may move during autofocus operation.
• マニュアルフォーカス（MF）： To focus manually, set the camera to manual focus mode. Rotate the focusing ring on the lens barrel until the subject appears sharp in the viewファインダ。

3.2 ズーム

To change the focal length, rotate the zoom ring on the lens barrel. The lens maintains its physical length during zooming and does not change focus when the focal length is adjusted.

3.3 絞り制御

This lens features a constant maximum aperture of f/4.0. When the aperture ring is locked at f/32, the camera body controls the aperture setting. Adjust the aperture through your camera's settings.

4.2 ストレージ
