Since it's pretty cheap in Korea, I sent all my prime lenses and my new Canon 60D to be calibrated at the local Canon service center so they can be "matched" to the body.
If I install a newer updated Canon firmware, or update to the Magic Lantern alternative firmware in the future, will I lose all of the service center settings?
Also, is the adjustment made mainly in the lenses and/or the body? I can't get a clear answer on this online. My Korean isn't so great so I can't get a good answer from the service center either.
