i don't believe the 50D is in the same class as the D90...doesn't it compete with the D300?
in terms of image quality, they're all more or less the same. the 50D has better noise handling than the XSi, i can't speak for the D90. the thing about 40D having less noise than the 50D is a pointless argument...oh no, there's a smidgen more noise at 100%! no one will notice in a print, much less in a 600x900 image in your web browser.
anyways, the most noticeable advantage of the 40/50D over the consumer bodies is build and ergonomics.
You can measure that the IQ in some aspects is lower. You're right that in many cases, the difference is practically not relevant. In general, stuff like noise curves are not relevant for most applications these days -- especially if you compare cameras of the same generation.If you check out the forums at http://www.dpreview.com you'll see that the claims of lower image quality for the 50d vs. 40d have largely been dispelled.
28 mm on the wide end is unsuitable for cameras like the 50D.Ok, well i guess this info would help. The canon 50D comes with a 28-135mm Lens. The nikon D90 comes with a 18-105mm Lens. These are what i would be starting with in each of the cameras because that is what they come with.
Nikon and Canon don't really have directly competeing models, except the 1Ds III and the D3x, and even then there is a pretty big price difference.
IMO here is how the models "stack" in terms of price and performance between Nikon and Canon crop factor DSLRs, from low to high:
D40
D60
Rebel XS/ 1000D
Rebel XSi/ 450D
40D/ 50D
D90
D300
Above this it gets even more complicated. The 5DmkII isn't really comparable to the D700 because of the megapixel and speed difference, the 1D III isn't really comparable to the D3 because of the ISO performance difference, and the 1D is still a cropped sensor, and again, the D3 isn't comparable to the 1Ds III because of the megapixel difference.

well, i know the D700 is a mix between a 1D and a 5D, which is why so many Canon shooters like it so much.
According to those who use both the 40D and 50D, there is no image difference because of noise, since noise can be corrected with software. Both cameras also incorporate NR, but I have never had the need to use noise reduction with my 40D. What I do instead is to select ISO speeds that produce less noise than the next, and if there is noise in any of my images, I reduce it with the noise filter in PSE6, or with Neat Image's.Megapixels don't matter at all, especially the difference between 15 and 12 is, in practical terms, rather small. On the other hand, the image quality of the 50D is lower than that of the 40D in some respects (e. g. noise), simply because each individual pixel is smaller.
The OP makes the usual mistakes noobs do: they focus on the body instead of glass. They think crappy lens + 15 MP body is better than a decent lens and a 12 MP body, because 15 > 12.
My advice is: get a smaller body, e. g. a (used?) 40D or a 450D if he goes Canon or a D80 on the Nikon side. All cameras have large viewfinders (compared to smaller models) -- a features that is a lot more useful than 3 additional MP. Couple that to a decent lens, e. g. a Tokina 16-50 f/2.8, and a real flash and you're much better off.
That was my first reaction too, but if B&H's prices are any indication, it would appear that Canon is having a rough time selling the 50D. It is priced at ~$1200 body only while the D300 is at $1500. The D300 has held pretty steady at that price. The 50D was introduced at a similar price point, but has been dropping. Within the Canon product line, I would guess that the 5DMkII is competing from above while the 40D is competing from below and not leaving much on the table for the 50D.
The D700 is a Nikon body, and is the D3 imaging components in a D300 body with a unique viewfinder.
Both Canon and Nikon are having problems selling their cameras at the moment. The ones that are selling faster are entry level cameras such as the XS, XSi, XTi, and then the 40D over the 50D. A lot of D40 to D200 are also selling on the Nikon side, but for both companies their sales have come to a halt recently.
Get the D90 without the kit lens, your wasting your money, get the D90 for $900 or whatever the price, then get the 18-55mm for a basic lens, and a 50mm F1.8 lens, those are 2 great starter lens.
Don't compare kit lenses.
Do you have a link to prove Nikon body sales are at a halt? They might be slowing down, but price wise they have raised their prices due to the yen. Even then, Nikon reps say they doing doing pretty well.
The 50D, however, has seen its prices go down even though the D300 is older. The D300, like someone has said, has stayed pretty steady at $1,500-1,600 even though it is 1 1/2 years old. I talked to someone at B&H recently (bought a new lens) and they said D300 (which I have) sales are doing pretty well at their sale even with this poor economy.
I'm not saying you are a liar, but a link showing what you said would be appreciated.

I think it's safe to say that sales of most all consumer luxury goods are slow right now, yes.
After doing a bit more research on the 50D, I was in error about it. It's not aimed quite so squarely at the sports/action shooter as the D300 is, nor does it appear to be as robustly constructed. Also, the original list price was $1300, so the current price of $1200 is in line with that. It's basically an enhanced 40D. I'm a little surprised that Canon sells both bodies as they seemed to be aimed at the same group of buyers.
Right now the 40D gives you "more bang for the buck," but the 50D offers a few things the 40D doesn't including camera/lens micro adjusting, movie clips (whatever it's called), more pixels, and a few other things. Both are similarly constructed, and include magnesium bodies with some weather resistance. The differences between the 50D and 40D are shown here:

Eh. It took a few months for the 20D to fade away when the 30D was released, and it was only a few months ago (prior to the 50D release) that the 30D was still a current model, sitting next to the 40D on the Canon website.
I know, I looked at that as part of my research. I don't see why Canon is keeping the 40D in production. The two bodies are essentially in the same price bracket, with the 50D updated to be more competitive with the latest features found in the market. I find these models being sold simultaneously to be confusing. Nikon is very clear about which body is the entry point into their system at the enthusiast level - it's the D90.
FWIW, the D80 and D200 are out of production and soon to be gone from inventory, so I do not consider them when trying to understand Nikon's product direction.
