PTZ1A225U-IRA-N is the cheapest 25x Starlight with this feature.

My SD59225U-HNI has PFA in Focus & Zoom (PFA on or off).

My new SD49225XA-HNR has it.

This model does seam to focus much faster now than the older model and might I ask is it still noisy on panning and tilting as I live with a house at each side of me and the neighbour could hear this late at night when I was playing.

It has a small wine but its not to bad. I can't hear it unless its silent most of the time, but its right over my couch. I only have my phone so I couldn't run it and record so I set it around 1" from the PTZ.
