I bought one of these docking stations for my Sigma 35mm Art lens. The focal point was slightly off at certain apertures, so I thought it would be easier to buy one of these than to mess around self calibrating in camera. I plugged everything in and updated firmware, then unplugged it and the lens is fine now. I didn't have to adjust anything in the calibration menu. Did the firmware update calibrate the lens without my interference? If so, that was easier than i thought. Thanks for any input..
