Some simple sample images that I took with my new Sigma 85mm f/1.4 DN on my Sony a7R IV. The distortion is quite crazy, so I can't wait for a correction to be added for this lens in Lightroom. It's optically outstanding wide open in the center and excellent throughout most of the frame. It's about perfect between f/2 and f/2.8. I'm hoping to see an updated 35mm f/1.4 DN as well, so I can add it to my AF kit (don't worry, I'm leaving a spot for the (hopefully) future CV 35mm APO).
