Steps:

Bug1:
situation:
I fight 2 enemies.
I lock-on to one enemy and use the d-pad to select the other one and press the A-button very shortly afterwards.
Result: camera is completely zommed in (I didn't touch the right stick)

Bug2 "sticky-cam":
situation:
I'm in a cave in witches drop (and some other places I don't recall) fighting an enemy whom I locked-on.
I zoom out, camera touched the wall. (LB still pressed) I try to zoom back in, camera doesn't move or at least doesn't zoom in but slides at the wall.
This also occasionally happens when the cam hits the ground
(happens alot when locking large enemy)
