In this Sony a7 III vs Sony a7R III Review, we compare the full detailed specs of these two mirrorless cameras from Sony, to see how they perform, helping you decide which is the best camera for your needs and your price budget.

Sony have been on a roll in the past year, starting with their Sony a9 camera release in May 2017. This compact mirrorless camera was aimed at high end action photography, thus came at a steep price of $3,498.00 on Amazon.

The a9 has really given the old top dogs, a run for their money, especially the likes of the DSLR cameras from Nikon and Canon.

While not many average consumer photographers bought into the a9 due to its expensive price factor, it was a big indication of what was to come from Sony.

Only 6 months later, in November 2017, shortly after the Nikon D850 release in September 2017, Sony released the a7R III, to compete with Nikon. The a7R III is a high megapixel camera, aimed at landscape, product and fashion photographers.
