TTArtisan Tech (HK) Co., Limited is one of the many optical manufacturers that have emerged in China over the past 10 years. The company is known for its inexpensive manual photo optics.
Her new full-frame lens 7Artisans 9mm F5.6 is no exception – also with manual focus. It has so far been announced only on the official 7Artisans Weibo page . This is an ultra-wide-angle lens, but not a fish-eye. However, its optical design of 16 elements in 11 groups means it’s not exactly a simple product.
Optical design
What’s the most unusual thing about him? MTF data. If this is really what this lens is capable of, then we are talking about very good optics.
MTF Charts
Yes, it’s not autofocus, but who needs autofocus on a 9mm anyway? The body is metal, the aperture control ring has clicks, the design is quite nice.
