Hey, ich have the Canon T6i/750D with the Sigma 24mm 1.4 Art lens. I also bought the Sigma USB Dock and tried to calibrate it. I haven't had problems with the first three calibratable distances (0.25, 0.35, 0.6) but when I shoot at distances which are further away than those like 2, 5, 10, 20 meters the focus isn't where it should be. How to calibrate those distances? Do they count as "infinity"?
