You are correct, that would make a big difference. If a person were working
in the lower reaches. But that's sensitivity. And my main point is, that
with the R7 having a shutter that not only gives 1/2 stop steps, which
automatically gives one more accurate control over exposure, it's also
infinitely variable in automatic modes. The R6 (and M6 for that matter)
only give us accurate settings in whole stop steps. (Say that 10 times fast!)

I disagree with unanimity.
