The NiSi teaser I reported two weeks ago was for a new 9mm f/2.8 APS-C manual focus lens - now officially announced in China. The lens will be officially released for the rest of the world on September 28th.
This is NiSi's second lens - a few months ago they announced a 15mm f/4 ASPH lens (currently in stock).
