The WonderPana FreeArc is a special filter system for special lenses, and the Ultra Wide Angle, Tilt Shift, and Fisheye lenses that Fotodiox supports can benefit from our line of custom WonderPana filters. But did you know that we have a WonderPana mount for the Zeiss Distagon 15mm f/2.8? The Zeiss 15mm's tulip hood presented a unique design challenge that we met with a custom version of the WonderPana FreeArc. Check out our Fotodiox YouTube and Facebook pages to see this system in action. #Fotodiox #wonderpana #ZeissDistagon15mmf2.8 #Zeiss15mmf2.8 #Zeiss15mm #ultrawideangle #filterforZeiss15mm #filtersystem #NDfilter #145mmFilter #ND1000 #photographyfilter #landscapephotography #architecturePhotography #tower #filter #FortSheridan #iPhone6s #wideanglelens #WonderPanaFreeArc #FreeArc
