I’ll wait for a scientific test over someone’s opinion or feeling. DP Review was not as glowing, nor Manny Ortiz, although all agreed it was an impressive AF system.
A Rebel type of camera vs the "best" Z9.
Also faster Raw shooting than the Z9.
Pretty impressive for under 1K.
No one does actual "Scientific" testing anymore. And even if equal, still amazing that a Rebel level camera has the speed and acuity to match the Z9 in many common parameters.
