7artisans 25mm f 0 95 vs voigtl nder nokton 17 5mm f 0 95 aspherical?
Both are fast, manual-focus primes with no stabilisation, so the choice comes down to framing and mount.
The 7Artisans 25mm f/0.95 is made for APS-C, but it also mounts on Micro Four Thirds, Sony E, Fujifilm X, Nikon Z, Canon RF and L-Mount. On APS-C it frames like about 38mm full frame, and on Micro Four Thirds about 50mm. It's the more flexible lens, and the one to pick if you might change systems.
The Voigtländer Nokton 17.5mm f/0.95 is Micro Four Thirds only. It frames like about 35mm full frame there, so it's the wider of the two. If you shoot Micro Four Thirds and want street or documentary views, I'd choose it. If you want a more standard, portrait-leaning view, the 7Artisans is closer to that.
