Not to be confused with 7Artisans ;~). The real name of the company is Shenzhen Mingjiang Optical Technology Company, located in China, and they appeared to start out as a maker of manual focus lenses for Leica M-mount cameras. They've now expanded their lineup to include other mirrorless cameras. TTArtisans lenses are generally available via eBay and Amazon.
