Sigma announced that it will hold a presentation this coming Wednesday, September 30th at 9 p.m. JST, which translates to 8 a.m. Eastern. An English version of the presentation will be shown via YouTube here.

There is confidence among those who monger rumors that Sigma has a 105mm f/2.8 macro to announce, although there will likely be more, as the announcement spoke of “products” in the plural.
