Canon EOS R8

82%of 67 owners recommend
82% recommend · 9% neutral · 9% don't
Owners praise
  • Autofocus and subject tracking are consistently called exceptional, with owners describing it as jaw-dropping, phenomenal, and "sticks to the object like glue," often noted as better than rival bodies at the price
  • Compact, lightweight body with surprisingly good ergonomics and grip for its size, making it comfortable to carry and shoot with all day
  • Exceptional value for the price, with owners repeatedly saying it over-delivers for its price point and is the best budget/entry full-frame option available
Owners complain about
  • No in-body image stabilization (IBIS), which several owners call the single biggest reason to hesitate or to consider the R6 II instead, even though most say lens/digital stabilization compensates well enough
  • Battery life is weak, with multiple owners describing it as "bad" or "horrible" and a recurring reason people look at the bigger-battery R6 II
  • Only a single SD card slot, so there's no in-camera backup redundancy, a repeated point of comparison against dual-slot bodies like the R6 II
