Sigma CEO Yamaki has been interviewed by Fengniao. They

Question: Will the art series 70-200 f2.8 lens, which is eagerly awaited by domestic users, be released this year?

Answer: We have heard about it and are working on it, so we hope to see it sooner rather than later. In fact, we have been thinking about differentiating this lens, hoping to bring something different to users, which is why we have not launched it yet.
