Auto hands free calibration only works on a limited number of cameras - my Canon 5D Mark IV is one of many that do not - meaning you'll need to set aside about 15 to 20 minutes per calibration. Then you must trust the software as for some reason the target appears too blurry to be of any use visually ( they claim this is because it's cropped).
Right now this is not an option, but we do have a solution coming that will allow wireless control of all cameras that we support. However, right now you can control FoCal from an iPad or equivalent as long as the camera is connected to a computer, so you can monitor and run tests remotely from the camera.

Can´t even come to Step 2; not possible to connect...(Nikon D750)
Can this be done without using tethering cable? like wirelessly with the wifi

can you use this for zoom lens at the W and T points
Thanks
Yes - you need to run the calibration twice for each extreme (ie; at 24 mm and again at 105 mm).
