From Fotodiox:
MARCH 29, 2016 –Fotodiox Pro, creator and distributor of several lines of specialty solutions for videography, cinematography and photography, has announced the Wonderpana FreeArc XL - a comprehensive filter system for the Canon 11-24mm lens. Ultra wide-angle lenses, like Canon's extremely wide 11-24mm lens, are usually impossible to filter due to their bulbous front lens element, lack of filter threads and potential for severe vignetting with typical filter solutions.
The WonderPana FreeArc XL, however, is the latest in Fotodiox’s custom filter system line and is designed expressly for the Canon 11-24mm lens. Its aircraft aluminum lens collar allows photographers to attach a custom series of massive 186mm filter options, like ND 4-1000 and circular polarizers.
The WonderPana filter system has been a worldwide success since its debut, particularly among landscape and architectural photographers and filmmakers. To suit Canon’s ultra wide 11-24mm lens, Fotodiox re-engineered the WonderPana FreeArc to create larger "XL" versions of the mounting system and custom filters to maintain the same level of flexibility and creative control as the acclaimed original.
Durable and lightweight enough for hand-held shooting, the WonderPana FreeArc XL can be ready at a moment’s notice to answer any image challenge that require filters. It can even remain installed full-time on a photographer’s lens as a critical layer of lens protection.
Additionally, photographers can add the WonderPana WP80 Filter Brackets to the WonderPana FreeArc XL to mount one or two square graduated filters at the same time as a round filter. Measuring 200mm x 260mm, the WonderPana FreeArc XL's square filters are the largest commercially available in the industry today, available as both soft and hard-edged graduated filters at .6 and .9 ND – perfect for meeting any shooting conditions head-on.
The WonderPana FreeArc XL is available now for $229.95.
The Fotodiox WonderPana FreeArc XL is available on Amazon.
