MI熱靴(Multi Interface Shoe)是索尼公司於2012年9月推出的一種熱靴接口,物理上基於ISO518規範[1],可以觸發兼容閃光燈,但同時通過前端附帶的金手指提供額外功能,除了配合原廠燈實現TTL功能外,還可以支持麥克風、GPS等與相機交換信息。
MI熱靴用於替代索尼之前繼承美能達單反系統而獲得的i-ISO熱靴,為標準冷靴附件,與單點熱靴產品提供更好的支持。索尼公司在之後推出的相機與攝像機產品上以此來作為熱靴標準配置。
索尼在2005年接收柯尼卡美能達公司相機事業部門,沿用其機型於1988年開始配置使用的iISO熱靴。因為物理上與ISO518熱靴不兼容,對於通用性附件支持不好,及希望增加新的功能,索尼公司於2012年9月隨α99一同,發佈了新款的MI熱靴(Multi Interface)接口[2],字面為「多接口熱靴」。
