Replace the original IOP element on your Optimo Prime lens to combine different filters for a variety of effects with this IOP Internal Filter from Angenieux. In order to combine multiple filters, the IOP internal filter has been developed to replace the internal element in the lens, so you can combine it with optional rear filters, iris cartridges, and front filters for endless creative effects.
This Black Pro Mist 1/8 Tiffen filter is made from glass and helps to reduce overall contrast and better control the flares and highlights while helping to smooth facial blemishes and wrinkles without any loss of sharpness. It is installed inside the lens using expert tools using a separately available special IOP tool kit. The filter install is reversible to restore your lens to its original configuration. The filter comes in a soft case.
