Lens distortion

Delhi, Ontario



Its interesting how a zoom lens can distort distance. The two images above are of the same bridge, the top image was taken with a 300 mm zoom lens and the lower one with a 17 mm wide angle lens. Clearly the bridge in the lower image looks longer, but it is the same bridge. In fact the lower picture was taken from further out on the bridge than the upper one.

This also causes any defects in the rails to be exaggerated quite a bit, making the rail look much rougher than it really is.
