85 1.8 vs 85 1.2

[Keith B]

Focused on one given spot with my 85 1.2 @ 1.2 = 1/125. Then bumped up to 1.8 = 1/60.


I'll let the brains figure out the decimals. I know it something over 1 stop. Obviously the 85 1.8 may expose differently.

Realizing the 1/125 and 1/60 may skew the numbers, I tried a scenario where 1.2 was 1/320 and then 1.8 turned out to be 1/160.
