Thanks for this. Three days ago I acquired my X-T2 and several of the lenses for which there is a firmware update. So, just starting to get to know the system. Permit what may be a dumb question: I get the notion of updating the firmware of a camera body. However, I don't quite get updating firmware for a lens. Do lenses themselves contain "software" or does a lens firmware update really amount to a further update of the firmware in the body? The Fuji firmware update instructions don't say anything about having the lens mounted on the body when doing lens firmware updates.
Would be interested to understand this!
