DxOMark has published the results of their findings on the optical performance of the Canon RF 28-70mm F2.0 L USM, the data can be found at the DxOMark site. I have written the lens review based on the same data of it, which can be found at a different page on the DxOMark site here. It’s a high-speed zoom with a constant F2.0 aperture and it has impressive optical performance overall, but be warned it’s not cheap.
As usual, the review talks only of the optical properties. We do not comment on handling, build quality, AF or other subjective areas. It’s an idea to look past the overall score – it’s just a way to rank the lens/camera (i.e., system performance) and it has only been measured on the 30MP Canon EOS R, so it won’t appear that high in the database comparison chart.
