To be honest this camera will probably get negative reviews regardless of how well it performs. There are so many negative reviews of the EOS R purely based on specs.Rather than slagging off this camera, why not wait for the real use reviews
you could put up and shut up, and just buy a Sony
ANY weakpoint to a Canon body is what people will focus on. The Slanted lens did a real world test of the EOS R vs A7RIII and Z7 and the EOS R matched the Sony in all the IQ tests and beat the Nikon in them. These real world tests are what matters and not what is listed in specs.
