However, it would be very uncomfortable as (sole) basis for exposure - Imagine shooting with both the EOS 5D II and 5D IV and having to remember that the IV's SNR decreases more linearly than the II's, thus it effectively has a steeper sensitivity-curve when changing between higher ISOs. Not that this is up for debate, but just saying. Thanks for bringing this up! | |

| Apr 18, 2018 at 19:34 | comment | added | Darren Ringer | I was seeking further clarification on how ISO is calculated (w.r.t. SNR) and was surprised to read all the intricacies involved, but at least in some cases it is directly calculated by SNR (and in other cases is more related to the dynamic range of highlights). Anyone reading this answer might want to check out en.wikipedia.org/wiki/Film_speed#Measurements_and_calculations | |
