The verdict
For a $100 premium, the Canon EOS R8 provides a larger full-frame sensor, whereas the Sony Alpha 6700 includes 5-stop in-body image stabilization.
Choose the Canon EOS R8 if you prioritize low-light performance and high-speed action, as it features a native ISO of 102400 and a 40 fps electronic burst rate. Its Dual Pixel CMOS AF II system also functions down to -6.5 EV for precise focusing in dark environments.
Choose the Sony Alpha 6700 if you require a rugged video-centric hybrid with 5 stops of stabilization and 4K recording at 120 fps. The weather-sealed body and 560-shot battery life make it more reliable for extended outdoor sessions.
