Ttartisan 35mm f 0 95 vs voigtl nder nokton 35mm f 0 9 aspherical?
Both are manual-focus 35mm primes for APS-C, and on a Fujifilm X body they frame and blur almost the same. Each gives about the field of view of 52mm on full frame and about the depth of field of f/1.4.
The difference is mounts. The Voigtländer Nokton 35mm f/0.9 Aspherical only fits Fujifilm X. The TTArtisan 35mm f/0.95 comes in Sony E, Fujifilm X, Nikon Z, Canon RF and L-Mount, and it also works on many full-frame bodies in APS-C crop mode, at fewer megapixels.
If you shoot Fujifilm, I'd pick the Voigtländer for its name and build. If you might change systems, or want one lens that works on several bodies, the TTArtisan is the more flexible choice. For a 35mm starting point generally, see the street guide.
