Question for ya:
How does your R5 ISO stackup against the 90d? I ask as you're limited to F8 (which is fine for probably the majority of the day).
From my experience with both 70d and 80d, anything > ISO400 = things really drop off a cliff, not end of the world, but it's noticeable.
I know this is apples/oranges, but I'm curious if you can comment on what ISO's your able to get away with having come from the 90d, and also just keeper rate?
