Sony A7 vs A7 II vs A7 III: How do they compare?

Sony A7 on the palm of a hand

When it was first introduced back in 2013, Sony’s original A7 was a big game-changer – squeezing a full frame sensor into an interchangeable lens camera that was smaller than a typical DSLR of the time, especially the sort of DSLR wielded by professionals.

Also new and unusual at the point it was released was that this new series of Sony cameras adopted the smaller Sony E-mount that was first used for the brand’s now discontinued ‘NEX’ compact system camera line up. Offering both high quality plus the convenience of portability and usability, it’s not so surprising that the A7 and its successive Mark II and Mark III siblings have increasingly found favor with photo enthusiasts and professionals alike.
