Well, I finally acquired a fish, something that I had been eyeing for a long time.
I was leaning close to a wall for photos of street art. With a fisheye, you get closer than Robert Capa would say "close enough".
A couple came by. I saw that she also had a camera, aiming at the wall and stepped back to give her space. She gave me a huge smile and said "my lens is very wide". I peered closely and I thought I saw a Canon fish.
