Watch the birdie...
OK John, I'm willing to be educated - what have the 40D and 400D in common at a component or a design level?
The other day, for example, I was able to get much better shots of a Great Egret in full sun - blinding white breeding plumes, perfectly exposed without turning the background into a dingy, dark thing. Switch HTP on, point, click, easy as that. Very[/i[ impressive.
........ If you are doing (for example) a scene with very bright white clouds making interesting shapes such that you don't want to blow the highlights out, there is a use. Another one came in handy for me last week and again today: landscape scenes with white salt lakes.

Please let me put aside the context of this thread briefly just to get your opinions on the settings you might use to brighten a big bird ...
(a) perched on a rock against a bright (grey sky) background
(b) gliding above rocks against a bright (grey sky) background
I use Rebel + Canon EF 100-400 IS.

IMHO, there is a clear choice: If you're doing landscapes, get a 5D. If you're primarily interested in wildlife, get a 40D. The pixel density is highest on the 40D, and since you'll be cropping most wildlife shots, you'll have more pixels to work with. The 1.6 sensor factor means your lenses are effectively 1.6X in focal length, which is the same as spending thousands more on lenses. The pixel density (173px/mm) on the 40D is the same as the ($8000) Canon EOS 1DS Mark III.
With the 5D, you'll have less pixels for the typical cropped wildlife shot, but for landscapes you'll have more pixels (because you won't be cropping as much) and a wider variety of available wide-angle and "normal" lenses.

Happy Snapping ,In fact, it's not even a re-made 30D: every last thing about the 40D is completely new compared to the 30D, and is so different to the 400D that they might as well be by different manufacturers.
I cannot see that myself - I have both and reckon there is not a lot in it as far as noise is concerned. I have read scores of reviews and comments on the 40D but have never come across anyone making a claim like this.From seeing test photographs looks like the 40D is at least 50% better at noise handling in all ISOs over the 30D. Which is enough to sell me. I.

To my eye it looks loads better.
That's fair enough then if that's the way you see it. If I was really pushed to say what had the best low noise at say ISO 800 I would say that the 30D is very slightly better.To my eye it looks loads better.
