The main difference in operation between video shooting and still photography lies in
the focus settings.
For still photography, once the focus is set, it generally remains unchanged.
However, in the case of video, frequent adjustments to the focus may be necessary
depending on the subject.

While automatic focus is an option, there are instances where intentional changes to
the focus point are required, necessitating manual control.
In such cases, operability becomes crucial.

Photography involves the use of lenses specifically designed for video (cinema lenses)
and a focus dial.
Cinema lenses come with a pre-engraved focus ring, and it seamlessly matches with
the gears on the focus dial from the outset.



Video撮影とスチール撮影の操作で異なるのはフォーカスの設定です。スチールは一旦設定
すれば、それでOKですが、Videoの場合には被写体によっては撮影中フォーカスの変更が
時として頻繁に発生します。
自動焦点の場合もありますが、意図してフォーカスポイントを変更する場合には手動と
なり、その場合には操作性が要求されます。
写真はVideo専用のレンズ（シネレンズ）とフォーカスダイヤルです、シネレンズには
最初からローレットが刻んであり、フォーカスダイヤルの歯車とピッタリ合います。
