Backfocus

Always I was wondering if my 24-70 lens was sharp. Today, then at least a test setup designed to test whether the focus lens is suffering from back or front focus.
Downloaded the card, the camera lens at an angle of 45 degrees and the full open F AV 2.8 and focus on the center focus point.
After verification established that the lens front and rear of the center is equally sharp. The depth of field is progressing well.
So again one less worry. You really want to know once.

Then the lesser sharpen photos are probably my shaking hand :)
