This is a set of images I took to try and compare the 40D to my current elderly 300D. Fist thing to say, the 40D is so fast and responsive. Turn on time, and focusing speed are a lot better than my old camera.

Next photo's were taken in the shop doorway with my 17-40L while the assistant kept an eye on me lest I did a runner. 40D at 0 compensation, 300D @ -2/3. Instant extra point to the 40D.

Test are taken with the cameras on auto white balance f10 on the lens @17mm. RAW images auto processed via lightroom. No sharpening or levels. also images shown are real pixel size. I will load a mod showing the original scene.

40D JPEG were a disappointment (camera on factory default large JPEG). Images from RAW look cleaner and sharper. at first I thought the 300D was a lot sharper, but you need to re-size the 300D to get to the same viewing size. (hence some 300D images at 2 sizes.)

Noise wise the 40D is a lot better @ ISO1600

Why am I doing this, well trying to decide if I get a 40D now or save longer for 5D.

Conclusion @ ISO100 biggest change is response time/functionality, though there is a resolution advantage with the RAW files. Up the ISO and the later camera wins hands down.
