Gerald Undone: EOS-R5/6 have two stops less dynamic range than the Sony A7sIII. And he couldn’t bring the A7sIII to overheat

Gerald Undone is now becoming my personal review guru :)

He published the full Canon EOS-R5 and EOS-R6 review. Let’s start from the good part. They are near perfect cameras for photographers. But many do keep comparing those cameras with the new Sony A7sIII and if you want ot have a reliable video recording tool than the Canon cameras are quiet problematic:

  1. Canon still lags behind the Sony sensor tech. The EOS-R5/6 have two stops less dynamic range than the Sony A7sIII
  2. Overheating is bad but the real issue is the recovery time which cannot be shortened with any tricks (vent and ice cooling). On the other hand his Sony A7sIII never overheated
  3. What I didn’t expect: IBIS has some pretty bad wobbling.
