What is the ttartisan 25mm f 2 good for?

The TTArtisan 25mm f/2 is a small, manual-focus prime for APS-C cameras. On Sony E, Fujifilm X, Nikon Z or L-Mount it frames like a 38mm lens on full frame, and f/2 gives about the depth of field of f/3. That makes it a good everyday walkaround lens for street scenes, travel and people shown in their surroundings, with a little background softening.

I'd pair it with a body that makes manual focus easy, such as the Fujifilm X-T5, the Sony a6700 or the Nikon Z50 II. It has no autofocus and no stabilisation, so you'll focus by hand and rely on good light or a fast shutter speed. For how focal length changes the look of a portrait, see the portrait lenses guide.
