Up until the 80s ish most proper cameras were made mostly of metal. Some time in the early 80s a lot became plastic. For reference have a look at the difference between something like a Nikon F3 and then the F90. I think it’s quite a good name as a lot of these cameras were very good at taking pictures, they just didn’t feel as robust in the hand.
This is why most pros use Macs. Most Apple screens are pretty good without any manual adjustment.
