I would be surprised if not given the failure to identify where actually manufactured coupled with statements like "Our products are built to our high-quality standards in some of the largest global production facilities in the world. All of our design, engineering, and quality management is done internally in Germany."
If I had to guess I would say that the ED's might be made in China and the HDs in Japan, looking at the prices, although even the EDs have magnesium bodies and aluminium eyecup tubes so maybe both ranges are made in Japan.
