The AstrHori 27mm F2.8 lens, priced at $126 (199 euros), offers excellent sharpness and AF performance, along with compact design. While vignetting and distortion are notable drawbacks, it has good color rendition and good bokeh at F2.8. Comparatively, it is like the Ulanzi / 7 Artisans ones but better than competitors like TTArtisan.
