zoom lens distortion?

Taken in a straight line to the side. Alignment was performed using a photo taken with a zoom lens on an object located far away. I photographed an object about 15m away at 300mm, but the result that seems to have occurred has occurred. Is there any cause for this?

The lens used Canon EF70-300mm F4.5-5.6 IS II USM
It looks Reverse and distorted.
It looks like a normal attached image. ![](https://support.capturingreality.com/hc/user_images/9K0CXMPdR5NWdO5k1p_yNw.jpeg)
