I agree that the 40D images need a little more work in PP than those from my 20D did. However, is your assertion based on any other
observations than the softness ( it seems just "the obvious thing to blame" ) or is there other info to support it? It's real hard to get good solid believable info specifically
about the AA filter....
Part of the problem is Canon's Digital Photo Professional. All images from multiple bodies are now SOFTER using DPP 3.0+ compared to DPP 2.2 when editing photos not at 100%. Also, the resizing mechanism in DPP sucks. The problem is the 40D is not supported by DPP 2.2, and a lot of people are "boxed in" to the horrible DPP 3.0+, and it makes their entire RAW collection look softer at default settings. There's also a massive view bug un portrait orientation causing image loss.
They really destroyed that program. I can gaurantee you that if DPP 2.2 supported the 40D, you would see a drastic improvement in image quality in that program at non 100% levels. I've tested this with multible bodies and lenses. It's sad that Canon cannot get this right. In fact, using 20D, Xt and XTi images in 2.2, and seeing them in 3.0 +, there is a GIGANTIC difference in IQ.
What you need to do is not rely on DPP 3.0 to judge your images. Adjust the color and exposure, then save as TIFF and look at the image in Photoshop. Make your other adjustments there.
I have to say, as a big Lightroom 2 fan, I'm not happy with the preview quality there either - although it is better than DPP 3.0+ (but not as good as DPP 2.2).
