On a very wet morning I visted Littlehampton, a small port on the South coast near Chichester to take a series of photographs using lens of different focal lengths. The mission was compromised by driving rain that made changing lenses hazardous so I restricted myself to only using 2 lenses, a 16mm – 35mm wide angle and a 70mm to 300mm telephoto, all taken from the same viewpoint. A selection of the images are included below and show that, whilst the subject (the union flag) becomes closer the relationship between the flag and other items in the frame remains constant.

Fig. 6 is a crop from the initial 16mm photograph (Fig. 1) showing that the captured image is identical to to the 300mm photograph in terms of the relationship between objects in the frame.
