1DX III vs R5 AF

[Fast Glass]

Perhaps, but I tested this with the 50mm f/1.2 and the Canon 24-105mm f/4. In every lens the PDAF outperform the DPAF significantly in low light. In bright light it was fine, but even with indoor light the PDAF was clearly superior.

Not to say it was bad, but when your standard is the 1DX III that is a very high bar indeed to surpass. So I am not exactly disappointed but more so surprised that nobody mentioned it. On one discussion I posted this very same thing another person did actually know this and said it was because the AF sensors are much larger than the pixels used in DPAF.

But what intrigues me is a real world comparison between the R5 and the 1DX III.
