As well as being shown the production of the Fujifilm X-Pro2 camera, we were also lucky enough to find out how the XF 35 f/2 and new XF 100-400mm X-series lenses are made at Fujifilm's Sendai factory.
To avoid contamination of the lenses, a strict Cleanroom Suit protocol is followed in this part of the factory, causing much mirth among the assembled journalists.
Again, the production process is surprisingly manual and labour intensive, with a small team of workers (one line for each lens) taking around 3 hours to produce the XF 100-400mm lens from start to finish, and around half that time for the less complicated XF 35mm f/2 lens.
The completed lenses are then laser-engraved, inspected, spot-checked and finally packaged up, again all by hand.
Fujifilm also conduct their own in-depth target testing of sample lenses, which we weren't allowed to photograph for confidentiality reasons.
Here is a gallery showing the full Fujifilm X-series lens production line from start to finish.
