Hi everyone, I just purchased the canon 10-22mm lens and the 85mm f1.8 lens and I want to run some tests on them to find any defects and to measure the quality. I was just curious what tests you guys typically run on your new lenses. I am looking for a thourough, controled test. Thanks for any tips. Justin

I use this one. http://www.photo.net/learn/focustest/

I printed that little line chart and put it on some posterboard then put it about 15' away at 45 degree and then test all my lenses. It works good.
