Canon EOS R vs Sony a7 III Review

The Canon EOS R has a bit of wow to it with the launch lens line up. The 28-70mm f/2 looks like an amazing lens and might convince some to give the system a try. Tony has decided to compare the Canon EOS R to the Sony a7III and most of what he found isn’t all the surprising, but I think the EOS R fits a little bit between the a7III and a7RIII.

To start off with Tony doesn’t think there is a clear winner, but he lays out some pretty clear differences between the two. For that reason I organized some bullet points from the above video to help you keep track of his opinion. It certainly seems like he should greatly prefer the Sony a7III.
