Stock lens calibration
  1. Good mornig everyone,

I recently bought a Samyang 85mm f1.4 AF for Sony FE. Since I have the lens station, I connected it to see if there was any update to push. In the lens dock there is also the focus calibration menu and there I noticed that it was set to -1. Since the lens is (teorically) factory new, is it possibile that samyang itself have calibrated the lens with the same software during the quality check and then sold it? Should I be worried?

Another more technical question: does changing the focus calibration affect the minimum focusing distance (in the microscale)? I don't know a lot about lenses, but I would imagine that the calibration consist of some micro adjustments to the focus range itself possibly?
