This May TTArtisan introduced the hand-focused a full-frame 90mm F1.25 lens equipped with a Leica M mount. To achieve a large maximum aperture at a focal length of 90mm, large diameter optics had to be used, so the weight of the lens exceeded 1 kg.
This week, the manufacturer added five more variants of the specified lens to its catalog. They are equipped with Canon RF mounts, Fujifilm GFX, Leica L, Nikon Z and Sony E. The optical design of the lens remains unchanged. It has eleven elements in seven groups, including two high refractive index elements. The 10-blade aperture ranges from f / 1.25 to f / 16 in steps. The minimum focusing distance is 1 m. The lens is designed for filters with a diameter of 77 mm. The largest diameter of the lens itself is 81 mm, and the length, depending on the mount, ranges from 96 mm to 107 mm. The manufacturer notes that the variant for Fujifilm GFX cameras is characterized by noticeable vignetting, since the image sensor in these cameras is larger than the full-frame one.




Interestingly, any of the new TTartisan 90mm F1.25 lens options are priced at $ 435, while the original Leica M mount retails for $ 740.
