The main difference between a lens with 18-135mm focal length and a lens with 18-55mm focal length is the range of zoom they offer. The 18-135mm lens has a longer zoom range, allowing you to zoom in closer to distant subjects compared to the 18-55mm lens. This means the 18-135mm lens is more versatile for capturing a wider range of subjects at different distances.
