Fotodiox WonderPana 145 ND Kit for Sigma 12-24mm f/4.5-5.6 IF HSM II ASP Lens

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! The WonderPana Neutral Density kit arrives with two filters that reduce the amount of light entering the lens by 4-5 stops, allowing for slower shutter speeds. This also allows for smaller lens apertures and/or slower shutter speeds giving you the ability to create amazing photos. By prolonging exposure times, the neutral density filters create the effect of movement in your photos by making anything that moves blurred or ghost-like (clouds, water, etc.). The filters may also be used on cityscapes to blur people or traffic. Neutral Density filters may be stacked together or used with other filters to help you get the creative image you want in almost any lighting situation.
