Click on the camera model in list to toggle visibility. Zooming is enabled. Use the resize box to resize the chart and list.
To share a chart consider getting a link with the link button rather than or in addition to simply using a screenshot.
Note that _12 indicates 12-bit data and _14 indicates 14-bit data.

Notes:
Read noise in DNs have been converted to input-referred read noise in electrons.
The conversion is for analog gain only. Digital gain and other signal processing are supressed.
These raw values are not appropriate for comparing camera models because they are not adjusted for area.
Flat spots in groups of three in the analog region usually indicate where digital intermediate ISO gain is present.
"Hi" ISO values can behave strangely once signal processing such as noise reduction kicks in.
