The latest miniature PTZ camera from Panasonic offers 4k HDMI output as well as performing very well in HD mode.  Obviously PTZ cameras of this size do have limitations and but if you need a budget UHD 4k camera for use with 4k LED screens, 4k live events or within a larger UHD 4k production this is just the tool for the job.

It has an excellent zoom range and very similar functions as the AW UE60.  Its easy to set up via a single LAN cable and supports POE+ just using one LAN cable for power, control data and HD-SDI video output with embedded Audio.
