Laowa argus 25mm f 0 95 cf apo vs ttartisan 25mm f 2?
Both lenses are 25mm primes for APS-C cameras, and both are manual focus with no stabilisation. On Sony E, Fujifilm X or Nikon Z bodies, each frames like a 38mm lens on full frame.
The difference is aperture. The Laowa Argus 25mm f/0.95 CF APO gives about the depth of field of f/1.4 on those bodies, so it's the one to pick for low light and soft backgrounds. The TTArtisan 25mm f/2 gives about f/3 there, which is sharper edge to edge at a stop you'll use more often in daylight.
The TTArtisan also covers more mounts, including L-Mount and Micro Four Thirds, while the Laowa lists Sony E, Fujifilm X, Nikon Z and Canon RF. If you shoot a system outside that list, the choice is made for you. Check the focal length converter if you want to compare depth of field on your own body.
