Kase 58mm to 72mm Magnetic Circular Step-up Ring

Kase

The Kase 58 to 72 mm Magnetic Circular Step-up Ring enables you to attach magnetic filters to small lenses that have a 58 mm filter thread. It is specifically designed for the 72 mm circular magnetic system and helps in minimising vignetting as you stack the filters. This step-up ring prevents the need to use a separate magnetic lens adaptor.
