As an rectilinear ultra wide lens, the 14mm F1.8 DG HSM | Art can create cool perspective effects. The concrete wall in the foreground is twenty feel tall, about eight feet wide on the open side and about 150 feet to the rusted container on the right side. My bike gives a sense of scale. And of course, the nearby Lighthouse is much, much taller than the the Mortar Battery wall. The Battery wall exhibits two-point perspective with the straight up and down line of the wall corner anchoring the composition. 1/80 F14 ISO 100.
