Focus test trick
Using the Jeffrey's Focus Test Chart, taking the test shot in Raw, one can open it on Photoshop Camera Raw and moving the black slider to the right causing the blacks to turn bright blue for easy reading on the focus centering for calibration. Also zooming will improve the view indicating very clear the difference from the center focus reference point. Regards: Oscar
