Must say that I agree with the supply and demand theory(a proven one i should say).
However, I think the major factor is down to one word: Internet.
Sure, the internet was here years ago, back when great cameras cost less than half of what they sell for right now, but it was at a time when technology was just starting to become more accessible. People were just starting to get DVD players to replace their VCDs. I guess you could call it "privilege" back then.
Then the inevitable happened, internet became part of everybody's lives.
When was the first time the thought of "Google it" came across your minds?
Well I like that camera which i just saw a stranger holding, I want to know more about it- Google it.
Ooh! It's wonderful, I want to buy it, how? Google it...
The trend passes from person to person, and eventually, everybody uses this way to do transactions, which accounts for the demand, while those who want to clear their house of some antiques also turn to the internet, filling in the supply.
I guess you could call it an "Evolving" cycle really. After acquiring the camera, the person uses it, finds that he is bored of it, back on the internet it goes. Only this time, the demand has increased! So he could sell it for more.
Then we come to this day where sellers simply couldn't care more, want to know how to price this item? Just price it as everyone is doing it!
Do you think the prices of certain things would go down eventually? I certainly hope to believe so, but from what I see, they only fluctuate until a flaw is detected about the product, then the prices really come down.
I should add that this is not entirely true, as some people that I know still prefer to stick to the tradition of going to a shop to try out a product before buying it. This is because they simply do not trust the internet. You could call it a "backfire" alright. Even many of us feel skeptical about prices for used items sold online nowadays.
Personally I caught the shutter bug in 2010 and went out to get a 550D, where I stepped into film land in mid 2012. I guess you can say it was the peak when things are going for more already? Well it isn't any less now come to think of it.
Some random blab from an experience point of view. I know that my years in this hobby could hardly be called "experience". Nonetheless, feel free to correct me!🙂
