Sony A7

The original Sony A7 launched in late 2013 alongside the A7R as the world's first compact system camera with a full-frame sensor — an achievement that changed the camera industry permanently. Its 24.3MP CMOS sensor with 117 on-sensor phase-detect AF points delivered far more practical autofocus performance than the A7R, making it the more versatile of the two originals. At roughly half the price of a comparable DSLR and significantly smaller, the A7 proved that full-frame quality did not require a large body — and launched a product family that would redefine professional photography.
