Fotodiox WP145-Core-SM1224II-Cap WonderPana Filter Holder for Sigma 12-24 mm F-4.5-5.6 EX DG ASP HSM II Wide-Angle Zoom Lens & Ultra Wide Angle Lens Filter Adapter

The WonderPana is a revolutionary lens hood filter system, which allows photographers to use filters on their Super-Wide Angle (SWA) and Ultra-Wide Angle (UWA) lenses. The system helps create the right lighting balance when capturing images using your UWA and SWA by giving you the ability to use filters on certain lenses where it was not possible to do so before. The WonderPana core unit doubles as a metal hood which gives added protection to the front lens element and the plastic built-in hood that is on many SWA/UWA lenses. The core unit is what provides the photographer a place to attach filters and a dedicated heavy duty snap-on lens cap to protect your unprotected lenses. The WonderPana System is a perfect fit for panorama, nature, architectural, fashion and event photographers, as well as, analog and digital filmmakers. The WonderPana 145 System will work with all Fotodiox Pro 145mm round filters; including Multi-coated UV filters, Circular Polarizers and Neutral Density 4, 8, 16 and 32 filters. So whether you just want to protect your expensive SWA/UWA lens (UV Filter), darken the scene for longer exposures (ND4/8/16/32 Filters) or remove reflections and enhance colors (CPL Filter) the WonderPana 145 will allow you to grab more creative control than ever before!
