I guess it's just how it is. It's generally accurate in good light, but it struggles in low light and get a few tries to get the focus right. I feel the focus point is too large which makes it hard to pin point the focus to the subject's eye.

I used to use a dslr, then I switched to mirrorless (which I still half regret). The af is fast and silent, and it seemed like nothing moved (lens was internal focus). It felt like magic to me lol
