[QUOTE="GracieAllen, post: 670876, member: 41283"] Does Focal replace the multiple distance/focal length calibrations done in the Sigma dock, getting rid of the need to shoot images at the different calibration focal lengths and distances? How does it do that? Am I correct that Sigma had some valid reason to provide the ability to do up to 16 individual microfocus calibrations, or is it just a marketing thing? In any case, given that at the moment I DON'T have Focal, can someone who's done the calibration with the Sigma dock provide their process? Or confirm that I'm correct about having to go back and forth between dock and tripod multiple times for each focal length and distance? [/QUOTE]
