Product Description The Free Arc provides the freedom to use and rotate 66 and 145 filters on your Wide and Ultra-Wide Angle Lenses. Because of the construction of these lenses, it's normally impossible to install filters as there are no filter threads, in addition standard filter sizes are not large enough to adequately cover the lens's wide angle view. The Free Arc changes all that by providing a complete kit for mounting our collection of both round and square filters. The all-metal Core attaches directly onto the lens with a secure mounting system. With The Core in place, you can now mount any of Fotodiox' s new 'slim line' 145mm round filters. The Free Arc system is a perfect fit for panorama, nature, architectural, fashion and event photographers, as well as, analog and digital filmmakers. Box Contains Rotating Filter System Holder
