In this video I put the Nikon Z8 head-to-head with the Canon R5 Mark II as “the best 45 MP camera,” and I’m doing it the way I always do it: with my own gear that I paid for. I’ve been using Canon on the channel for the last 3+ years (R5C, R6 Mark I, and now the R5 Mark II), and I also know Nikon inside out (Z9, Z8, ZF, Z6II, Z7II, and more). So this isn’t a spec-sheet video—I’m pushing both cameras in real tests, including buffer behavior, ISO noise, color, dynamic range recovery, and autofocus. I start with price ($3,800 for the Z8 vs $4,300 for the R5 Mark II) and then get into the stuff that actually matters. In my buffer test, the Z8 barely buffers, while the R5 Mark II can lock up in repeating chunks even at 20 fps—so for longer action sequences, I’d take the Nikon. In dynamic range recovery (both underexpose-and-push and overexpose-and-pull-back), the Canon loses color and falls apart faster, while the Nikon holds onto color information better. Autofocus is where things got spicy: in my tests I got more eye tracking and faster detection from the Z8, and Canon still seems to struggle when the subject isn’t just a plain t-shirt. But Canon does bring advantages for long-form video: better battery life, a multi-function hot shoe with accessory options like XLR, and even an optional cooling system if you pay extra. Bottom line: your lighting and your use case decide the winner.
