Alter 55mm Rapid Filter System, Includes Lens Mounting Ring, Black

The Rapid Filter System is a hinged lens filter adapter designed for all levels of photographers & videographers. Engage & disengage your lens filters in a fraction of a second and keep up with ever-changing light conditions. This standard RFS features a fixed lens diameter and filter diameter. For example, an RFS 67 will have a lens thread diameter of 67 and a filter thread diameter of 67.

The RFS & RFS+ are the streamlined solutions to a commonly experienced problem among photographers and videographers. Keep your filter accessible at all times via the revolutionary hinged design and enjoy the fastest way to engage and disengage your lens filters.

Both are precision machined from aerospace aluminum and include a built-in light shield, preventing light leak. Choose from either the RFS (fixed lens and filter size) or the RFS+ (integrated step-up) for optimal performance when paired with your lenses and filters.
