What is causing these fuzzy photos!?!

go get your sensor cleaned

Has the camera been dropped?

 

Can you do this Clorox test at F8 with both camera's using a tripod?

 

I saw something like this happen just one time and it turns out that the sensor moved out of position, so if it

were my camera I would test both bodies with the same lens at F8. If the clorox bottle remains out of focus

needless to say you have a camera in need of an adjustment/realignment.

 

I concur that the boys hair is sharp. This is my reason for asking you to test the camera's at F5.6 to F8 to F11.

this test will surely guide you to the actual problem. Because of the boys hair being sharp this leads me to a very shallow depth of field and the camera's are just fine.

 

Keep us posted!

<p>Why?<br>

I do not understand the reason for that advice.<br>

What relevance does sensor cleaning have to the issues that the OP describes?</p>

<p>@Melissa, I know you've said the camera was on autofocus, but have you accidentally changed the diopter correction on the viewfinder? I don't even know if the 40d has that, but if set wrong it may prevent you from seeing the scene correctly, and affect your handling of the camera, which in turn may explain some of the suboptimal results.</p>
