In order to effectively improve the image degradation of the fisheye lens edge, we designed the TTArtisan M11mm F2.8 into 7 groups of 11 pieces. Even when the aperture value is F2.8, it can meet the high image quality requirements of professional users for photos and videos.

50mm f/1.4 ASPH adopts the optical structure of 10 elements in 8 groups, including an aspherical lens, an abnormal dispersion lens and 8 high refractive index lenses. Such design ensures the image quality from the center to the edge, working well with 60 million pixel digital.

The lens structure of TTArtisan M21/1.5 is 11 sets of 13 pieces and the length is 70mm. The large aperture of the F1.5 is matched with the wide-angle focal length of 21mm. In the humanities theme, the background can display information while obtaining a spatial stereoscopic effect. A wide enough perspective can be obtained in the creation of scenery.

The 35mm f/1.4 uses the Sonnar structure. The Sonnar structure is a classic optical structure that occupies a dominant position in the medium telephoto and ultra-telephoto lenses. The equivalent full frame is about 52mm, and the closest focusing distance is 0.28m. Good food is more than enough.
