NiSi 70mm Filter System
The 70mm Aluminum Filter Holder Foundation Kit from NiSi is designed for use with Micro 4thirds cameras and smaller mirror-less cameras such as Olympus OMD, Sony and Fujifilm. It is a similar design to the 100mm V5 system with the CPL being incorporated into the main adaptor ring. The holder has two slots so you can use two 70mm wide filters plus a polarizer in any configuration.
Filters available for the 70mm Filter System include:
Neutral Density (ND) Filters
Graduated Neutral Density Graduated Filters
Reverse Graduated Neutral Density Filters
All NiSi 70mm Filters are made from high quality optical lens glass offering no loss in sharpness, Ultra low colour cast, Anti glare Nano coating and are water and oil resistant. When using neutral density filters the camera is vulnerable to infrared light which can cast an unwanted red color to your picture.
Nisi added the infrared protection coating layer to this filter which helps to eliminate the infrared light through the lens resulting in an image with natural color. This filter also has the NiSi Nano coating which reduces reflection and adds a waterproof coating to the filter making them incredibly easy to clean.
