"Collector" sounds like a collector of valuable art - but for cameras that is not really an option. The vast majority of cameras on the second hand market are film, which most people don't "collect" for the purpose of having some sort of asset that will be worth millions in a few years' time. I agree some cameras, a few, are "collectable" for their rarity and quality, but is a Pentax ME Super today a "collector's" item? I mean, it's not going to be worth half a million ££ in a couple of years.
Does the OP mean "hoarder"?
For me, the rise of digital has meant that I am finally able to buy some of the cameras I used to lust after - my weapon of choice nowadays being a Contax G2, which I could NOT have afforded when it came out. The same goes for other cameras I used to get serious GAS for years ago, but could not afford.
Does that make me a "collector"? No - except in a very minor way. I am just curious to buy old film cameras really cheaply and to have the chance to experiment, which I could't do before.
The future looks dire, but try to be positive - it's not all black and white, so don't be so negative.
