Canon EOS R5 Dynamic Range. Canon's first dual gain sensor

Bill from PhotonsToPhotos has completed his testing of the EOS R5 and it has some surprising results.

This is Canon's first true dual gain sensor - which means that when the second gain kicks in you get a DR "bump". It also means to maximize the DR of this camera from a purist standpoint you need to shoot at both the lowest ISO and also again for shadow recovery at the ISO "bump" which in this case is ISO 400.

The PDR looks so similar that I had to double-check to see if Canon said they developed and made the EOS R5 sensor - and yes they have.

Dual gain sensors were primarily Sony sensors in the past, and Sony got the technology to do it through Aptina. It seems that Canon has either finally gotten permission to use the IP rights or have created their own solution.

One thing is for certain - there's no longer any dynamic range loss when using a Canon camera compared to any other brand. But the Internet has moved on to overheating anyway ;)
