I'm amazed with some of the detail in the photos here. I have to work harder than I was expecting with my R5 and RF85 to get very detailed shots, and it's also proven to be a bad lens for action (for me). I've tried using it for dogs and it fails pretty bad every time. Too slow to focus, and it has a very hard time finding dog's faces and eyes at 1.2. Seems to work better closed down.
Best scenario I have found for the lens is the studio with flash, though I still have to raise the sharpness considerably.
