Sigma factory tour

Back in July of this year, we were in Japan for the launch of three new Sigma lenses, and the smallest full-frame camera we've yet seen, the Sigma fp. After all of the hustle and bustle of the product releases, we were granted an opportunity to tour Sigma's factory in Aizu, a couple of hours and a couple of trains away from Tokyo.

Sigma is unique in the digital photography industry in that it's still a family-owned business, and it controls most of its production line from start to finish, in one location, for both cameras and lenses. In fact, many workers at the Sigma facilities are 2nd-or-3rd generation employees, and the jobs that Sigma maintains in the Aizu region help sustain the surrounding communities.

Since the last time we visited back in 2015, Sigma has made some additions to its factory space. Let's take a closer look at how Sigma's lenses - and cameras - are made.
