A miniature lens driving apparatus includes a housing, at least two strings, an optical image stabilization (OIS) mechanism, and an autofocus (AF) mechanism. The OIS mechanism includes a lens holder. The AF mechanism includes an AF moving holder, an upper spring sheet, and a lower spring sheet. An internal connecting portion and an outer connecting portion of the upper spring sheet are connected to an upper end of the AF moving holder and a stationary part of the AF mechanism, respectively. An internal connecting portion and an outer connecting portion of the lower spring sheet are connected to a lower end of the AF moving holder and the stationary part of the AF mechanism, respectively. The two ends of each of the at least two strings are connected to the lens holder and a lower portion of the AF moving holder, respectively. An electronic image-capturing device is also disclosed. |
