TTArtisan Unveils the 90mm f/1.25 Lens for Six New Camera Mounts

The Chinese lens manufacturer TTArtisan is bringing its 90mm f/1.25 lens, previously only available for Leica M mount cameras since May 2021, to six other lens mounts. Now, the ultrafast prime will be available for Sony E, Nikon Z, Canon RF, L-mounts for full-frame mirrorless cameras as well as the Fuji GFX and Hasselblad X1D mounts for medium format mirrorless cameras.

As with the M-mount version, all six versions for other mounts feature 11 elements in 8 groups, including four sets of achromatic doublet lenses for high image quality. Other features include a 77mm front filter thread, a 10-blade aperture diaphragm, an aperture range of f/1.25 through f/16, a clicked aperture ring and it has a minimum focusing distance of 1m.

TTArtisan has said its manual-focus 90mm f/1.25 was designed to look and perform like a Leica lens, with a heavy build and creamy bokeh. The lens’s “high speed and the unique aesthetics of its depth of focus make this telephoto lens the first choice for portrait photographers,” the company states. “The angle of view is 27 degrees. It highlights the main body while avoiding the suffocating sense of space compression caused by the super-telephoto lens.”

“Dispersion is a common optical phenomenon, especially in fast lenses,” TTArtisan says. “Four sets of Achromatic Doublets are used in [the] 90mm f1.25 lens to significantly improve the chromatic aberration and the resolution performance, presenting excellent image quality. The spherical aberration of achromatic doublets is better than singlets.”

The manual-focus lenses all measure 81mm in diameter and the length ranges from 96mm for the Fujifilm GFX-mount to 107mm for the Nikon Z-mount with the weight of the lenses coming in around 1kg. Here is a sample gallery of images taken with the lens, provided by TTartisan:

The TTArtisan 90mm f/1.25 lens for mirrorless cameras is available for $479 through the TTArtisan online store, Pergear, and on Amazon.
