Tip for the use of auxiliary lenses, wide or tele, on a zoom lens. The tele ones are designed to be used only at the long end and vice versa for the wide converters.

That's generally true when the rear lens diameter of the converter is smaller than the front element of the lens it is fixed to. In order to reduce vignetting the rear element from the converter has to be bigger in size. Another factor that comes into play is the size of the front element of the converter. Unfortunately, a larger size also produces added weight.
