Marumi 58mm Variable ND2.5-ND500 Filter

Brilliantly creative and eminently practical, Marumi's variable neutral density filters are a dozen filters in one. Simply twist one of the polarised elements to smoothly darken the filter and reduce light levels without changing the colour balance. The filter is variable between a subtle ND2.5 (just over a stop) and an extremely dark ND500 (approximately 9 stops).
