Canon EOS R8 vs Sigma BF
The Canon EOS R8 and the Sigma BF side by side, computed from this guide's catalogue.
Which to pick
Pick the Sigma BF if you want a newer model (2025 against 2023), which usually means better autofocus and video and more lenses made for it in this guide (158 against 99). On these specs the Canon EOS R8 has no clear advantage: choose it if the price, the handling or a lens you own decides it. If you already own Canon RF or L-Mount lenses, the camera on that mount saves you buying them again.
