Manual Focus for PTZ
The auto focus on the PTZ is horrid to say the least. When I set up a Cruise Path it typically consists of 8 to 10 locations at varying focal ranges. The camera already takes significant time to get in the general area of focus when you zoom in or out for each location. That part probably cant be helped much. However once it gets in the general focus area, it hunts back and forth, passing optimal focus several times before locking in.
The mechanics of the lens should allow for setting the camera to manually focus so the user can set focus for each location. That would at least do away with the time consuming focus hunt.
