R3 “ISO” Let’s take a look how well the Canon EOS R3 holds up in high ISO settings. I am so impressed with the R3 when it comes to shooting at any ISO. I shared an image on my first post when I received the R3 for what I saw at 10,000 ISO in low light. You are going to love shoot this camera in low light and at high ISO’s. You will not hesitate to turn up your ISO. GO ISO HIGH ! #canonusa #teamcanon #canoneosr3 #canon_photos #mycanonstory #canonexploreroflight #canonmirrorless #nflphoto
