Ed's experienced powers of perception should not be under-estimated here!
It is probably correct to imply that the image is not quite right, rather than the lamppost is actually leaning, and that view would be supported by the optics (and probably by the Local Authority!).Ed is right in principle because (unless a large amount of this image has been cropped away from the bottom) the centre of the image is somewhere near the chimney of the middle building. So the camera must have been tilted upwards slightly when the image was captured, which would distort the perspective, causing the verticals to converge.
The telephoto lens being used would put the camera at some distance from the scene, so this effect is quite small, though more noticeable for the tallest verticals near the side of the frame. Even so, the tilt of the lamppost is minimal in this image, and so it really matters little whether it is corrected.
Cheers.
