Slightly off the main topic, but perhaps someone can answer a question regarding the cameras used in QT.
Most of them seem to be the same size as those generally seen in studios, yet I have noticed that QT also uses two very large cameras (one behind the audience and one behind the set) which look like the sort of thing you would normally have seen in the 1980s/90s.

Those are large box-lenses (which are also used in studios - but not BBC News studios where most people see cameras in-vision) which are more common on sports and events OBs and in larger studios as they have much higher zoom-ratios (100:1 wouldn't be unusual and you can go a lot higher than that).
Because they are so much bigger than the small 'ENG-style' lenses often used on lightweight cameras they are either used on 'full-size' cameras (which are a bigger body that can't be operated handheld and will always be mounted on a ped, a heavy-duty tripod or a sit-on crane etc.) or much more commonly in the UK they are used with lightweight cameras sitting in cradles that emulate a full-size camera. The use of cradles means studio and OB suppliers only need to have light-weight camera bodies in their stock and can flexibly deploy the same camera heads in both roles.
Box lenses can have much larger zoom ratios - i.e. they let you get a lot tighter from the same distance - so if you need to shoot a close-up or mid-shot from a long distance, you will normally use one. Where you see the two cameras next to each other, the one with an ENG-style lens will probably only be able to shoot wider shots than the one with the box lens on it. Looking at it, the ENG-style lens-equipped camera doesn't have an operator, so is probably a wide lock-off.
The camera behind the guests peeping out over the top of the set is almost certainly shooting audience questions and reactions (and needs a box lens to get decent close-ups from that distance)
The bulk of what you are seeing is the box lens. Nothing 80s or 90s about them - they now come in 4K flavours
https://www.canon.co.uk/lenses/uhd_digisuper_122/ Here's a state-of-the-art 4K 122:1 lens. That is likely to cost hundreds of thousands of pounds. ENG lenses are usually less than £50k (and sometimes a lot less - but will be much lower zoom ratios - nearer 22:1 or less, but often wider angle at the wide end)
