Choose if: You want full-frame quality at the lowest price in the smallest body. Best for stills shooters who don't need IBIS and can lean on Canon's excellent autofocus.
Choose if: You want the more capable hybrid. In-body stabilization, dual card slots, and a higher-resolution 33MP sensor make it worth the premium for serious work.

Spec figures from the makers: Canon R8 (canon-europe.com, checked 25 Sept 2026) · Sony A7 IV (sony.co.uk, checked 25 Sept 2026)
The Canon R8 is cheaper, but here's what you give up:
Worth the premium? Yes, if you shoot handheld video, deliver paid work that needs card redundancy, or want the extra resolution. The R8 wins on price, weight, and burst speed; the A7 IV wins on reliability features and versatility.
Winner: Tie. Canon for fast lock-on and vehicles, Sony for sticky predictive tracking across subjects.
Winner: Sony A7 IV. IBIS plus dual slots make it the safer choice for handheld and paid video; the R8 trades stabilization for a lighter, cheaper body.
For serious hybrid shooters: The Sony A7 IV is the more complete tool. IBIS, dual card slots, a higher-resolution sensor, and longer battery life justify the premium for paid and handheld work.
For budget-conscious stills shooters: The Canon R8 delivers the same full-frame image quality in the lightest, cheapest body here. Just accept the lack of IBIS and budget for extra batteries.
