Canon EOS R vs Sony α6600

The Canon EOS R and the Sony α6600 are both mirrorless cameras, but they use different-sized sensors that each come with advantages and disadvantages. The Canon is a full-frame camera with a fully articulated touchscreen and a larger, higher-resolution EVF than the Sony. It delivers better overall image quality and performs a bit better in low light. However, it doesn't have in-body image stabilization like the Sony camera, and it's less portable. The Sony also has a longer battery life and a faster continuous shooting speed for quicker burst shooting.
