Following financial losses, the hard disk division was sold to Seagate in 2011 in return for a 9.6% ownership stake in Seagate.

I won’t disagree with you there and your point is probably more correct now than it was when I wrote this article and when I was doing tests with my Nikon D100 way back when! Many modern digital cameras are applying corrections that you 1) don’t know about and, 2) cannot really take control of. I have a shiny refurbished Nikon D500 and a shiny new Tamron mm lens.
