A recent Canon media event provided a significant amount of hands-on time with the new Canon EOS 90D and M6 Mark II. Both are excellent cameras and while I look forward to bringing these models into the studio for a more in-depth look, I have plenty of information to share with you now.
First, the review pages are a work-in-progress but already loaded with information:
Canon EOS 90D | Canon EOS M6 Mark II
From those pages, navigate to the specifications and product image pages for detailed comparisons. Note that the specifications are also a work-in-progress and the camera side images remain MIA.
