The first season of The Bear is shot on old lenses. I'm not sure if they are also using old cameras but the outcome feels really cool.
I think it fits perfectly and elevates the feel of the show.
I'm not sure about the newer seasons though.
Edit: Apparently they used Panavision lenses.

It seems some are made with old glass and coatings but I'm having trouble finding specifics.
I'm looking forward to most of those shows. This is a pleasant surprise.
