These seven examples at f/1.2 were shot at very late dusk when I could scarcely see. However, the Canon EOS R does a wonderful job at f/1.2 in delivering a Live View image in full color, a sort of night vision device, but in color.
These frames give a good idea of what a miracle-worker the Canon RF 50mm f/1.2L USM is at f/1.2: crisp and clear imagery wide open—very impressive.
Includes images up to full camera resolution.
