Sony Alpha a7
The 24.3MP full-frame Exmor CMOS sensor paired with the BIONZ X engine captures 14-bit RAW stills from a lightweight 416g mirrorless chassis. It provides uncompressed 1080/60p video output, a tilting 3-inch LCD, and direct E-mount lens compatibility, making it a versatile and budget-friendly gateway to Sony’s full-frame system. This camera suits budget-conscious beginners and streamers who value full-frame image quality and portability over fast burst speeds and 4K recording.
