Canon 40D sharpness

On my 10 D when I use DPP I only need to move the sharpness setting to 3 to 5 when I do the same to get a sharp photo with the 40 D the sharpness setting is 5 to 10 is this normal or should I have my camera recalibrated.

I trust you were using the same lens and the same scene to do this test?

Sharpness has to do with many things and from the limited information you provided a slightly higher level of sharpening may be required for the 40D sensor as opposed to the 10D sensor. I would only get my gear calibrated if the body/lens combo was front or back focussing.

check your in camera settings first. For any picture style (including the default standard), the camera's sharpening can be changed. Some photogs remove all in camera sharpening and do it in post, others (like me) prefer some in camera sharpening knowing that a little will need to still happen in post. It's user defined so check you menu first, it could be that the 10D just did more in camera.
