DPReview posted the results of their tests on the Canon Canon EOS 80D‘s dynamic range.
The article is pretty interesting, and understandable also by non-engineers.
Previous Canon sensors have conducted the analogue to digital conversion step away from the sensor, an approach that contributed noise that limited dynamic range at low ISO settings (while still allowing the excellent high ISO performance that Canon’s CMOS chips built a reputation with). The sensors in the EOS 80D and EOS-1D X Mark II appear to have an on-chip ADC design that conducts the conversion within the sensor, shortening the electronic path and preventing this noise building up.
The results of exposure latitude and ISO invariance are striking. It was already known that Canon had a new sensor design (maybe also on the Rebel T6s, Rebel T6i and EOS M3 but I am not sure), now we have test results that confirm the new sensor design, and the better performance that this design delivers. The reason:
Canon’s previous design allowed electronic noise to accumulate after the amplification stage […], which had minimal impact at high ISO settings but limited the processing flexibility of low ISO files by adding noise that was visible if you tried to lift shadows or increase contrast. […] Now that it’s moved across to an on-chip column ADC architecture, we should expect to see further improvements in future generations as the design is optimised. Read the article…
