What is this weird distortion at the back of some images I took today? https://preview.redd.it/b4qe2fghm04d1.png?width=810&format=png&auto=webp&s=2a6f8ad32a7e7d5686ccb69548d6e8451bb5cc94 I noticed this weird distortion in the background of my images making the poles look wavy. I'm not sure what it is - was my aperture too low? Taken at f/7.1 on a 50-250mm Canon zoom lens.
