I will add that 'film cameras' were not called 'film cameras' they were called 'cameras'
Now that we need to distinguish between film and digital the need for terminology to do that has arisen. Analog versus digital is in common usage but no one is going to mind if you use film and digital.
These terms are called
retronyms – a new term to distinguish something that is no longer the current technology. "Film camera" is a retronym.
Consider "acoustic guitar. Once there were guitars and "electric guitars." Now there are guitars and "acoustic guitars."
Those of us of a certain age wore diapers when we were babes. In the 1960s along come Pampers and moms chose between diapers or "disposable diapers." Now today's moms choose between diapers or "cloth diapers."
We used to have 'phones and push-button (or touch-tone) 'phones. Later this changed to 'phones and dial 'phones. Today we have cells (U.S.) or mobiles (U.K.) and landlines.
Time marches on and language evolves along the way.
