Here is a noise comparison of the Sony a7R III Vs. Canon EOS R Vs. Nikon Z7 full frame mirrorless cameras.
From the result high-resolution Sony a7R III has less noise overall against the newly announced Canon EOS R and Nikon Z7. We guess the Nikon and Canon data is based on pre-production models so we can see the improvements later.
Canon EOS R : $2,299.00 (check price)
