Distinguished by its updated sensor design, the Sony a7 III is a well-rounded camera suitable for both photo and video applications in a variety of working situations. Refined for improved speed and low-light performance, a new 24.2MP Exmor R BSI CMOS sensor and BIONZ X processor benefit image quality, video capabilities, and AF performance. The a7 III also sports a revised body design, with a new touchscreen LCD, improved EVF, larger battery, and dual memory card slots.
