Mavica是Sony一种已停产的数码相机品牌，在**的中文译名“魔影佳”，于1981年8月问世。初期机种采用3.5英寸的软磁盘作保存媒体，解像度只有VGA的640×480，比现今照相手机的拍摄能力还要低，但在当年来说已是很好的解像度。后来的CD400、CD-500已采用8cm光盘为保存媒介，在当时记忆卡价格高昂的时代，获得不错的评价。「Mavica」取名于英语「Magnetic　Video　Camera」的缩写，意思就是「采用磁性保存的录像设备」。一般人以为Mavica系列只有数码数机，但其实这个系列最早期的产品，是一部于1981年生产的录像机。而这系列的摄录机后来亦改用CD作保存设备，而非磁性记录设备。

Mavica (Magnetic Video Camera) was a brand of Sony cameras which used removable disks as the main recording media. In August 1981, Sony announced the Sony Mavica as the world's first electronic still camera.

It was not a digital camera, as its CCD sensor produced an analog video signal in the NTSC format at a resolution of 570 × 490 pixels. Mavipak 2.0" disks (later adopted industry-wide as the Video Floppy and labelled "VF") were used to write 50 still frames onto tracks on disk. The pictures were viewed on a television screen. Otherwise, this camera is positioned as the "pioneer of the digital era".
