did you use R6? is there a significant improvement in mark 2? I will most probably not change my R6 (is it does not die or something) but it is interesting to know. and i am just charging my Classic to see will it help me to jump start back into more shooting :)

I came from the mirror 6D2 this is a big big improvement, the focus is amazing and ISO is really really good. And with the AI noise reduction, I can easy shoot on iso 20k
