Yes, prices change over time. At the time of the Leica X1 review, the D300s was over 2k, at the time of the 7D review it was 1800 dollars. Both prices taken from the reviews.
Obviously DPReview is able to dig out the current prices at the time of the review. So why is it so much more difficult to spend an additional 10 minutes at a place like B&H or Amazon to fgure out what other cameras you can buy in that price range? Even if the 550D drops 30% in prices and the K7 doesn't, that
still doesn't invalidate the comparison, because
at the time of the review you would be paying the same amount of money for the cameras. That is my point. When DPR reviewed the 50D, they compared it to the K20D, even though it had dropped from $1,200 to $800.
As for why I'm budgeting about a thousand dollars on a camera and another thousand on the lenses instead of spending as little as possible? Well, for one thing I live in a place where it's really cold half of the year, and generally raining constantly. And I like(d) to take landscape pictures. Annoying to do with an old, crappy Sony Cybershot P&S, but at least that one is easy to stow away when it starts raining at a moment's notice. I can always buy lenses later, but they do tend to be expensive if you want good quality.
So ... looking around, the K-7 seems to fit that bill quite well, since it's weather resistant and its kit-lenses are as well. That sets the price range including the 18-50 lens ($1,020 at B&H)). It's expensive for my wallet (I'd prefer to stay under $900), but it's doable. But what else can I get in that price range? Well, I could go down a bit and get second hand K10D, K200D. That'd get me even more glass at the cost of modern features like video as well as faster AF and lower pixel count.
So, I'm really looking for something that comes with a kit-lens and costs 1,020 or less. That sort of brings the A550 into the picture at 1,050. If I
really stretch my budget, I might be able to get the D90 or 50D kits, but realistically I need to go cheaper. A380, 550D, D5000, 550D, 500D and E30 fit those prices. If I go lower, I'm ending up with way too many to list, but just listing the dual kits:
- A230 or A330, 18-55 & 55-200
- E-620, 14-42 & 40-150
- K-x, 18-55 & 50 - 200
- A330, 18-55 & 75-300
- K-x, 18-55 & 55 - 300
- D5000, 18-55 & 50-200
- A380, 18-55 & 50-200
The dual kits are interesting, because I'd be getting more lenses, but I'm losing features.
Now, Canon has chosen to place their 550D at a price that is very close to that of a contemporary K-7 and maybe a D90. But for some reason that DPR aren't disclosing, they don't feel that these three cameras would be interesting to the same buyers. But for some reason the 150 dollar step up from the 550D to K-7 prices (at the time of the review) isn't possible, while the 170 dollar step up from the K-x to the 500D is (again, prices listed in the review).
The Sony A380 ($950 kit) was compared to the K-7 ($1,500 kit) and 500D ($895 kit) back in December 2009. Five months later the $979 550D is compared to the D5000 ($800 kit) and D500 ($800 kit) and the K-x (unlisted price, currently $521).
For some reason the A380 is no longer comparable to a more Canon 500D's newer and better brother, but the much cheaper K-x is. This makes even less sense, because the price difference between the A380 and the K-7 has decreased by about 70% in the mean time (120 dollars more than the 550D vs 550 dollars than the A380).
It doesn't even look like Nikon is getting that kind of preferential treatment. The only thing there is their semi-pros getting compared to the K-7, but that sort of makes sense, as that's the highest end Pentax.
It also seems to be a fairly new thing. The K-x was the cheapest camera in the entire "compared to" list. The K-7 is compared to the E-30 and Alpha700, but only in the list, not in the actual comparison. The K2000/Km is compared to cheaper cameras only (1000D, A200, E-420). The K200D is a mix ($600 to $700). Same with the K20D (range of $800 450D to $1,500 E3).
So why is it all of a sudden such a bad thing to cross these lines? It's not like that 1,000 dollar mark is magical. If it was okay to have a range of +
- $400 in June 2008 (K20D review, $1,200 kit), why is it all of a sudden a very bad thing to compare the similarly priced $1,250 K-7 to the $900 EOS 500D a year later?
