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.

Its a marginal setup issue, made "worse" by the impact of different angles shooting on to LED screens, which have multiple viewing angle luminescence issues.

Also teleprompters make a difference, so even if every camera was same model/cloned config, you'd still need careful manual adjustment to match non hooded cameras.

The PTZ phobia is a bit overkill, they're additional shot cameras without needing crew to reposition things on the studio floor, they're on air for a tiny amount and 99.9% of viewers won't notice a thing.

It's run-once news content, on shows full on zoom/teams remote interviews, iPhone mojo shoots with obvious lens issues, compressed LiveU pics, viewer submissions in vertical video uploaded to twitter with high compression, YouTube archive content etc. PTZ with marginal differences to full-size pro cameras really isn't an issue
