My first experience is a little bit ambivalent
Eye-AF is not working properly on my progressive lenses, just on one of my single vision glasses. Works ways better on my R3. Having no problems switching the AF point with my eye.
When the AF fixed an eye, it moves away from it after 2-3 seconds - even if the bird sits still.
Heavy battery drain (wrote another post in the forum)
The frontgrip gets very warm.
Recording pre-burst shots, the Body hung up 2 times when recording it to my CF-Express card (Lexar professional 1750MB/s)
Hoping, all these first experienced issues are blown away by coming firmware updates.
Question to all: Which video/article do you think is good for shooting birds on the R5 Mk II ?? (found one from Mr. Wegner/australia and Wild Alaska)
