Re: Please help me to choose a FF camera system (landscape, wildlife)

The lens isn't what keeps things in focus here, it is the camera. In fact the camera plays a far more important role in keeping things in focus - things like Eye AF, focussing 120 times per second, tracking across 90% of the frame.

If focus needs to be adjusted , the lens element needs to move, so lens can readjust 120 times per second? I thought camera can only evaluate focus, but is limited by lens autofocus motor.  Don't know about sony, but canon puts same autofocus system in entry level cameras than strips a few functions in firmware, remove option animal-eye, only keep human-eye, remove option to adjust field size, only full field in cheap camera, pay +$1500 dollar for those options. Maybe interesting for some, but expensive lens is safer investment, retains value much longer. If people shot birds for decades without this, why is 2020 camera software feature suddenly a must have?
