It is a great option for a bright, fast walkaround prime for X-mount shooters [...] Optically it's sharp wide open, offers pleasing bokeh, and has minimal chromatic aberrations. Autofocus is fast thanks to the use of linear motors, though video shooters may find the manual focus experience limiting.
