Sirui 23AS12E-B
The Sirui Sniper series lenses are widely praised for their outstanding value for money, delivering solid build quality and impressive image results at a budget-friendly price. Users highlight the fast f/1.2 aperture for excellent low-light performance and beautiful bokeh, as well as reliable autofocus for both photo and video work. However, some reviewers note that sharpness is not optimal wide open and that chromatic aberration can be noticeable.
