The fuzzy, out of focus shot Midlands Today use for their wide shot is an example of how not to use a PTZ.

A prime example, but even in the Norwich studio with its glorious HD, you can tell the switch between the two, as I said previously they remind me of CCTV cameras, in fact arguably some of them are better picture quality!

Edit: Here's two shots from Newcastle, an HD site

You can see the obvious artefacts of the 'fisheye' lens on the PTZ, as well as some strange issues with luminance.
