FotodioX WonderPana Absolute Core for Canon EF 14mm f/2.8L II USM Lens

Dedicated to the Canon EF 14mm f/2.8L II USM lens, the WonderPana Absolute Core from Fotodiox is a system of adapter rings to permit working with oversized filter holders and 145mm circular screw-in filters on this lens that lacks front filter threads. Besides the 145mm front filter ring, which permits attaching Fotodiox' 145mm threaded filters to the lens, this bundle also includes a 130mm front adapter ring for connecting an optional Cokin X-Pro filter holder and a 150mm rear adapter ring for attaching an optional LEE SW150 filter holder. The lens-dedicated design of these adapters does not interfere with the lens' focusing or zoom movements and each of the rings are constructed from anodized aluminum alloy for durability. Additionally, the adapters maintain unrestricted rotational movement of the filter holders, and the rings are designed to minimize the distance between the lens and holder to reduce unwanted flare or reflection.
