US accessory manufacturer Fotodiox has announced an XL version of its WonderPana Free Arc filter system for wide angle lenses that it says is designed specifically to allow users of the Canon EF 11-24mm F4L USM lens to use filters over the front element. The Canon super-wide zoom has no filter thread of its own and the front element is heavily convex, so fitting filters in the traditional way is impossible. The WonderPana Free Arc system positions a filter holder over the front of the lens that takes 186mm screw-in filters and/or 80mm rectangular filter sheets. The holder is enormous so that large filters can be used to avoid vignetting when the lens is used at its widest setting.
The Free Arc clamps the hood of the lens between its collar and the screw-on filter-holding cone, and provides a 186mm thread for the company’s screw-in filters. A set of brackets can also be attached to the cone that allow two square filters to be fitted as well. The system makes it possible to fit one round filter and one square filter at the same time, and the whole filter stage is rotatable so graduated filters can be positioned to suit the subject.
The Fotodiox WonderPana Free Arc XL costs $ 225.95 and the 183mm filters start at $ 99.95. For more information visit the Free Arc page on the Fotodiox website.
