Originally posted by Bagga_Txips Massive price drops after a year or two are part of a pattern that has been occuring for decades, especially in the field of electronic "toys", so anyone who buys anything like this shortly after launch should be aware that they are subsidising future buyers, and by buying they are accepting this. I am grateful to early adopters, they beta test the bugs away, and in the case of the K-3 mean that I will soon be able to buy for 600 dollars a camera that was pie in the sky for me when it was launched!
Sure, I bought a digital cable receiver with hard disk a number of years ago, the first model to feature HDMI if I'm not mistaken, and easily paid over 300 euros. Today you can pick them up for less than half the price. And the used market is being flooded with simpler models, starting as low as 35 euros.
With regard to Pentax though, I think there is more to it. Pentax cameras may be good value, but they don't hold their value as well as Canons or Nikons. You can still get a Canon 7D new for as "much" as 750 euros. Now imagine paying that much for a new K-7, which was introduced around the same time. I just did a quick search, and the asking price on used 7D's starts just above 500 euros. I saw one K-7 with an asking price of 220 euros, less than 7000 actuations and it included a lens.
Now, the 7D may be an extreme example. So let's look at the Nikon D7000. Asking prices are no lower than 400 euros. It was introduced in 2010, so let's compare it to the K-5. I have a K-5 here, which I don't actually use anymore because I got a K-3. But I don't think I would get one interested person if I asked 400 euros for it.
Which kind of leads me to another interesting observation. Everybody is saying that Canon and Nikon are so expensive. And if you look at prices new, sometimes they are (case in point: the new 7D Mk2). But over time, as you replace your body and sell of the old one, I think it might not actually matter that much, or anything at all.
The only question that remains (which may or may not be relevant to you): why do Pentax bodies lose their value so fast?
