Abstract
A follow-focus wheel assembly includes a supporting member, a follow-focus plate, and a follow-focus wheel. The supporting member includes a supporting seat and a mounting seat formed by extending outward from the supporting seat; the follow-focus plate and the follow-focus wheel are located on two sides of the mounting seat respectively, and the follow-focus wheel passes through a through hole on the mounting seat and then connects to the follow-focus plate in a rotatable manner. The supporting member is used for connecting an external structure, and the follow-focus wheel assembly is mounted in the external structure via the supporting member, where the follow-focus wheel partially extends out of the external structure when the supporting member is connected to the external structure. The follow-focus wheel assembly has a simple and compact structure, and can be miniaturized. It meets the requirement of performing a focusing operation with a single hand.
