Sony A7 Series
Sony's core full-frame mirrorless line — refined across five generations.
The Sony A7 line is the benchmark for full-frame mirrorless. Starting with the A7 II's landmark IBIS, each generation raised the standard for autofocus, video capability and value. The A7 III set the template that cameras from every brand still chase; the A7 IV and A7 V continued the refinement.
