Just goes to show what an incredible sensor that one in the 5Dc has always been, even today it's used as a benchmark. It's the reason why we always put up with some aspects of the build, that sensor would never ever let us down. Had two of them since they were first released. Only now buying a 5D3 cause one of my 5D's was dying even after a shutter and mirror box transplant, just dying of old age and many many frames.
Keep in mind of course in comparisons that the highest real iso of the 5Dc is 1600. I'd say from messing with many raw files from the 5D3 that the newer camera has about a 1.5 stop advantage however and this is important, the higher iso's are real iso's, the 5Dc never had an iso 3200 nevermind 6400, etc. We can only marvel that these are available to us now, for real, not just camera software pushed versions.
