I was using the EF 24-105 lens so I had a good range from widest to telephoto. I decided to use a small building within Victoria Park as my subject.
At 105mm telephoto, I had to stand much further away. The building looks flatter and compressed. Vertical and horizontal lines look more like they should.
At 24mm wide angle, I had to stand much closer to the building to ensure it filled the frame. This results in those parts of the building closest to the lens to look larger. The roof and sides move away from the camera; this is known as foreshortening. The chimney has been partially blocked from view due to foreshortening, and because I had to point the camera upwards. This gives the image more depth, but horizontal and vertical lines slope away from the viewer.
