Is the ttartisan 35mm f 1 4 sharp wide open?

I don't have a sharpness test for the TTArtisan 35mm f/1.4, so I can't tell you how crisp it is wide open. What I can tell you is that it's a very cheap, small, fast normal lens for APS-C, it's manual focus only, and on Sony E, Fujifilm X, Nikon Z or L-Mount it frames like a 52mm on full frame. Its page has the full list of compatible bodies.

If wide-open character matters more to you than clinical sharpness, my pages describe the Voigtländer Nokton Classic 35mm f/1.4 as soft and classic wide open. For background on what f/1.4 does to depth of field, see the aperture notes.
