7artisans 14mm f 2 8 vs ttartisan 14mm f 2 8 asph?
On the specs this site lists, these two lenses are twins. Both are 14mm f/2.8 primes for full frame, both are manual focus, neither is stabilised, and both mount on Sony E, Nikon Z, Canon RF and L-Mount. They frame the same way too. Every camera on one list is on the other.
The site doesn't cover build quality, optical performance or price for either lens, so I can't tell you which one is sharper. Check current prices and reviews, then pick the one that suits your budget and how it feels in your hand.
Both work well for wide landscapes, architecture and interiors on full frame. You can compare them here: TTArtisan 14mm f/2.8 ASPH and 7Artisans 14mm f/2.8. If you shoot APS-C, the focal length converter shows how the field of view and depth of field change on your camera.
