The test that I am doing is actually looking at a piece of Newspaper and the type at 100%. I did actually see the same thing at a local camera dealer with a 3rd body. I probably just need to shoot and not worry about what my lens looks like when shooting a flat piece of newspaper. What ae your thoughts.
My first thought is that most lenses are not optimized for close-up work, and I'm assuming you are shooting these tests at close to the lens' minimum focusing distance.
There is also the issue of making sure that the paper target and the film (excuse me, sensor) plane of your camera are both parallel to each other. This is critical because of the shallow DOF when using lenses near wide open aperture.
Both of these can introduce errors which can make your results less than useful.
My suggestion is to test your lenses under your typical working conditions. I'm sure you can find real-world situations which let you test your lenses' sharpness, flatness of field, etc. Then go out and enjoy your gear.
ps: if shooting critical closeups of flat objects (photos, paper pages etc) is important, then the best way is to use a macro lens on a copy stand.
