Kolarivision published their Nikon Z6 mirrorless camera teardown and disassembly pictures online (see also the previous Nikon Z7 teardowns) – here is their conclusion:
“Nikon follows the example set by Sony in some aspects of its design as well as it’s market philosophy. The cameras also improves upon the Sony A7 series in certain areas like cover glass thickness, weather sealing, and heat management. However, as we previously discussed, neither the Sony or Nikon cameras come close to the Canon EOS R in terms of beautiful design, and that’s a fact.”
