Buy it at http://sdp.io/S23
The Sigma 23mm f/1.4 lens is designed for Sony, Fujifilm and X-mount APS-C cameras. Because it’s designed for APS-C, it’s lighter and less expensive than full frame alternatives like the Sony 24mm f/1.4GM we compare it to in this video. You also get better image quality because the optics are optimized for the smaller image circle of an APS-C sensor.
