Well, monetary value is secondary to everything unless you're a dealer or a speculator hoping to turn a profit. Nobody else (apart from collectors) should buy a film camera unless they want to shoot film. For those who do (generally alongside digital), it's interesting that film gear is currently at least holding its value, including those manual focus primes. The flipside of this is that some of the gear is now becoming unaffordable. As well as cameras, there are cult lenses from the film era, sold at inflated prices, often to mirrorless users. Some of these lenses weren't highly regarded at the time, but now have a new market in people who enjoy their 'character'. Others were superb lenses then and remain so now, though in the meantime mass market lenses have come a long way. An unremarkable lens of the quality we expect in the days of 50 megapixel sensors may well be more than competitive with some of the legendary glass of the past.
