The main benefit of a multi-lens interchangeable set is that you get different coloured lenses fitting the same single frame for use with varying light or backgrounds and for shooting enthusiasts to help see different target colours. With over 75 different models, we have one of the largest ranges of interchangeable, multi-lens sets available. Options range from 2 up to 5 lenses.
