Our Verdict

Sony α7 III

Canon EOS R8

The Sony α7 III and the Canon EOS R8 are both great full-frame cameras. The Canon is newer, so its video specs are more up to current standards, and it's a more portable model. However, the Sony feels better built, has a better battery life, and includes dual SD card slots.
