On tripod, the touch screen. BTW: eye-AF handheld works great for me even in low light. Example: I take my grandson to a trampoline park called Urban Air. The lighting is terrible dark. Eye-AF picks up his little 3 year old eye from 30 feet away.
Wow... that sounds great that eye-AF works so well in low light. I have used an EOS R on a number of occasions - mostly during the day and in good light, though I also used it a few times in the dark. I was quite impressed at its ability to focus in low light. but I never did continuous (servo) AF or eye-AF in low light
So, thanks CFB for sharing your experience with that, which is very encouraging / promising to read of - that eye-AF performs so well, both locking focus and following in really low light. As I also have a 3 year old, they usually don't sit still for very long (unless they've got a screen-based activity they're focused on... lol).
