I've mentioned elsewhere on Fstoppers about my desire to lighten my camera bag for personal use. I recently got a Sony a6600 and bought the best zoom I could afford. (Sony 16mm-55mm f2.8)
While processing this image of the popular climbing area at Smith Rock, OR., I saw what looked like a bird near the middle peak. There was so much resolution that when I enlarged it the "bird" turned out to be a "slack liner" walking between two peaks.
