Sep 26, 2018 at 13:09 | comment | added | mattdm | @EdgarBonet Looking again, I'm not actually so sure about the original chart — the URL shows that from DxO as well. I can't make out exactly what the URL is, though; can you? Meanwhile, I'm also not sure if the "Sports" score in the chart I included is scaled by display area; the Overall chart definitely is, but the current DxO pages are unclear on this one. | |

The upward trend you see is perfectly consistent with the slide shown by the OP, which states “for the same display area, SNR has been improving”. | |

Sep 25, 2018 at 18:18 | comment | added | Michael C | It would be interesting to see the DxO chart with all of the lower end models that use 'recycled' sensors from their higher end stablemates (e.g. the basement entry level Canon T6 introduced in 2016 used basically the same 18MP sensor as Canon's top APS-C model, the 7D, did in 2009). I think the trend would be even more noticeable. | |
