In terms of lens mounting, what is the difference between the Zenmuse X9-8K Air and the Zenmuse X7?

The Zenmuse X9-8K Air now features a convenient lens locking lever. Once the lens is mounted, simply tighten the locking lever to securely fasten the lens and minimise vibrations. Before removing the lens, ensure that the lens locking lever is in the unlocked position. This mechanism provides added stability and ease of use during lens attachment and detachment.
