Some quick suggestions:

  • for action/sport shooting, the best features/price ratio is of Sony A7III.
  • For video, Canon is the worst, it suffers from strong crop factor at 4K, missing high frame rates at Full HD and missing sensor stabilization. Nikon Z6 is very good for video (and quite better than Nikon Z7), Sony A7III is also very good.
  • Nikon(s) and Canon models, being the first full-frame mirrorless models with the new mount, start with very few native lenses that can fully exploit new system capabilities, so maybe they are not yet the best choice if starting now from scratch.

Detailed characteristics of all these models together with links to most interesting reviews are available in LightPoint Camera Database: Sony A7III, Nikon Z6, Canon EOS R, Sony A7RIII, Nikon Z7.
