Looking for a Sony a7 III vs Sony a9 vs Sony a7R III comparison? Read our detailed specs comparison of the Sony Alpha A7 III vs Sony Alpha A7R III vs Sony Alpha A9 to find out their strengths and weaknesses, and decide which one to choose.

With its 24.2MP back-illuminated Exmor R CMOS sensor, AF coverage of 93% and 10fps continuous shooting, it’s a nice addition to Sony’s full-frame mirrorless camera offering.
